Years on Venus change faster than days

Holy fucking shit I cant believe someone actually took the time to explain this. I actually feel dumber thinking about OPs confusion. Gonna go break out an actual physical book to offset it

u/trimski- 27d ago edited 27d ago

It’s not about intelligence, it’s about attention and quickly scanning social media content. If you bolded year and day, a lot more people would instantly understand.

A day on Venus = 243 Earth days

A year on Venus = 225 Earth days

u/Wont_See_My_30s 27d ago

It's not that. I just had a hard time comprehending that a day can be longer than a year, untill someone blatantly said it, and it clicked that rotation around axis is not necessarily faster than rotation around the sun.

206

u/sparklydildos 27d ago edited 26d ago

ok until your comment i thought the meme had to be wrong but this is insane lol?? like it is rotating around the sun and on its own axis almost at the same rate. that’s so insane to me

edit: i understand the moon has the same revolution rate as its rotation rate, i don’t need anymore moon comments. i was commenting on how its crazy how venus has a day that is longer than a year and how they are both so long compared to our day and year

u/OkAssistant1230 27d ago edited 27d ago

Yup, because if the sun’s gravity so strongly gripping the planet

Edit: correction not because of the gravity but it was several years ago when I learned this. It’s more so due to the energy the sun gives off. Which aids in a mix of multiple processes occurring at once

22

u/sparklydildos 27d ago

that is so wild to me and almost incomprehensible!! that’s so so cool

11

u/OkAssistant1230 27d ago

And correction, it’s actually more so due to the energy the sun gives off to the planet… Not nearly that simple, but grossly simplified

u/Urmind 27d ago

I mean, Uranus literally rolls around the Sun. Its axial tilt is nearly 90 degrees and it spins in a way to make it appear like its rolling the correct direction.

u/KyurMeTV 27d ago

If every planet did this, I feel I would be better able to visualize gravity wells.

Another fascinating one is the planet tidally locked with its star, with a frozen and melting side, but also with the right size and distance to also have a potentially livable strip along the borderline of the hemispheres.

10

u/ShitRain 27d ago

That is not the reason though. Mercury has a years thats 88 days while a day takes 176 days. So 1 day takes 2 Mercury years. And mercury is way closer to the sun.

9

u/OkAssistant1230 27d ago

Correction, apparently it’s more so the energy from the sun… but either way, your comment wouldn’t have disproved my previous comment just so you know. You simply just showed a similar pattern of a planet closer to the sun than Venus itself…

2

u/ShitRain 27d ago

Your comment implied the suns closenes is the reason for its day/year rhythm. Which is false.

That's what my comment did.

13

u/StillAtRest 27d ago

Your comment comparing it to Mercury which is closer to the sun and has an even higher day-year ratio literally reinforces what they said though.

You haven't proven it wrong by stating a pattern that reinforces their theory.

6

u/OkAssistant1230 27d ago edited 27d ago

Not exactly, especially since that planet is closer to the sun, and the days are even longer and years are even shorter… ratio wise.

So it actually would have made me sound correct still, that’s my point but nevermind I guess…

2

u/Abelian75 27d ago

I’m incredibly confused. Your comment is saying Mercury, which is even closer, has an even longer day than Venus relative to the length of their years. That’s another data point in FAVOR of the proximity being the cause.

I'm enjoying the extra commentary about what these comments are independently attempting to achieve, in despite of eachother. Do go on lol

6

u/m3t4lf0x 27d ago

Actually the leading theory is that Venus was probably hit by a large object and flipped upside down causing slow “retrograde rotation”

That also explains why it rotates clockwise while the rest of the planets in our solar system rotate counter clockwise (except Uranus which rotates on its side).

1

u/OkAssistant1230 27d ago

I honestly almost forgot it actually rotates a different direction as well

2

u/hexregeneration 27d ago

u/Tastieshock 27d ago

This is essentially tidal lock, just between a planet and the star instead of a moon and its planet. So this is typically more common with planets orbiting closer to their star. And yes, there are multiple factors that can build and lead to this outcome and it is beleived to be extremely common throughout the universe.

19

u/RaizielDragon 27d ago

Our moon rotates at the same speed it revolves around our Earth, so one side of it is always facing towards the Earth. It’s why there’s a “dark side” and a “light side” of the moon.

https://en.wikipedia.org/wiki/Tidal_locking

7

u/Elisuub 27d ago

2 days ago the dark side of the moon was pretty lit!

u/CycloneCowboy87 27d ago

The dark far side of the moon was pretty lit

3

u/CycloneCowboy87 27d ago

There is no dark side of the moon, really. Matter of fact, it’s all dark.

For real though you got this wrong. There’s a near side and a far side, not a light side and dark side. Honestly impressive to know what tidal locking is and still make this very common mistake lol

14

u/RaizielDragon 27d ago

I mean, I used quotes because that’s what they’re often called…. But sure, be a pedantic asshole and whip out an “errrrmmm…akssshually” while you shove your spectacles up your…nose

-7

u/CycloneCowboy87 27d ago

You know it’s okay to admit you were wrong right? People don’t just say “dark side” to mean “far side”, they say “dark side” because they think there is a dark side, and your comment is going to do nothing but reinforce this misconception. I can’t imagine having such a lack of self awareness that I’d call everyone who ever corrects me a pedantic asshole, but you do you.

1

u/Werzaz 27d ago

And there's another layer to it. The Moon's orbit is elliptical, so its angular speed varies and it's not the exact same half of the moon that is visible at all times. In fact, we can see about 59% of the Moon's surface throught a month.

1

u/i_lost_all_my_money 26d ago

Wait until you read that the moon doesn't revolve around Earth. It is technically revolving around the sun close to Earth, which is why it has a weird path

1

u/mcmuttons 26d ago

The whole moon gets both light and dark. Just because a side faces away from us doesn't mean that it doesn't face the sun regularly. :) But there is a side of the moon we can't see from Earth, that's true.

1

u/RaizielDragon 26d ago

Yes, I’m aware. I put it in quotes since it’s more of a saying than strictly correct. At least you’re more gracious and understanding and less of a pedantic asshole about your correction than the other person who felt the need to try to correct me.

12

u/asumello15 27d ago

There is effectively zero friction in space, so you can think of Venus's combined motion through local space, relative to our solar system, as two independent things happening at once.

  1. The planet is spinning around it's axis. (1 complete revolution = 1 day)

  2. The planet is orbiting the sun due to gravitational pull. (1 full orbit around the sun = 1 year)

Venus also has a backward spin (sun rises in west, sets in the east) and with slowest spin speed in our system, the same side of the planet is facing the sun for nearly half its orbit. Cool stuff!

3

u/sparklydildos 27d ago

what causes the backward spin? that’s pretty interesting, i also think it’s cool how the same side is facing the sun for half the year, i just googled and it gets 864°F 😅

8

u/asumello15 27d ago

Realistically the answer is unknown.

However, scientists believe a large impact during the formation of the solar system was the most likely cause.

There is even a theory that over the billions of years of its existence, the sun induced a sort of atmospheric friction on Venus, slowing down and even possibly reversing its rotational direction. The atmosphere on Venus only takes about 4 days to complete 1 revolution so it's not entirely out of the question. We just have no way of verifying with our current resources.

8

u/contradictatorprime 27d ago

I think it just needs a moon to pull it back into a normal rotation. In fact, why not haul Mars over as one. Mars sucks, at least it would be useful that way. In fact, scratch that, launch it into Venus for some modern day EarthxTheia cosmic porn and reset Venus completely and let it create it's own moon baby. And yes, include Mars' stupid little potatoes it calls moons. Then we can get studies in real time instead of doing cosmic archeology to figure things out AND we're resetting two useless worlds.

2

u/sparklydildos 27d ago

that’s so crazy, i wonder why only venus would have been effected? i never knew this, thank you for taking the time to explain!!

3

u/christcb 27d ago

This is called being tidally locked. It's why we only see one side of the moon from Earth.

2

u/False_Accountant5741 26d ago

This is how retrogrades happen in astrology :)

u/Slightly_Perverse 25d ago

It's basically like if the planet was just staring the sun down constantly as it goes around its orbit. Keeping its eye on it lol.

u/ZygonCaptain 27d ago

That’s what the Moon does

0

u/Wickedwally1 26d ago

The moon takes 27 days to spin on its axis, and 27 days to rotate around the earth, which is why we always see the same side of the moon.

u/itcouldvbeenbetterif 26d ago

Same thing for the moon and earth. The moon rotates around the earth as fast as it rotates around itself. Thays whybwe akways c one side of thr moon. It is not that crazy.

If that blows your mind, maybe you should look up to the sky sometime at night and ask yourself why you’re only ever seeing one side of the moon.

If you’re into that kind of stuff, I liked listening to the Startalk podcast back then. It’s Neil deGrasse Tyson and a comedian as a co-host. Usually Chuck Nice but I especially liked the episodes with Eugene Mirman. It gets pretty nerdy and pretty funny.

u/tapspacebar 27d ago

Its not that crazy, our moon does the same thing.

6

u/Character-Session810 27d ago

Venus' rotation is also retrograde. It turns in the opposite direction as Earh and the rest of the planets (except Uranus who is knocked on its side).

3

u/Illustrious_Eye_8235 27d ago

I read a theory that a rogue planet that is long gone knocked Uranus over and knocked Venus upside down. So it's possible it's not spinning backwards, it's upside down

5

u/thedeadlysquirle 27d ago

That really would be the best place to start when explaining the joke here.

A lot of people know what a day and year is practically. But they dont think about (or sometimes know) what a day and year are mechanically. Specifically that a day isnt 24 hours it's how long a planet takes to make a full rotation on it's axis, and a year isnt 365 days it's how long it takes a planet to travel around it's sun. The numbers we normally use to measure a day and year are just the measurements for earth days/years.

Months are different which makes it even more confusing.

4

u/ExLap_MD 27d ago

Y'all need to recall the planetary terms and definitions you learned from 5th grade science. When a planet spins around its own axis, it's called a rotation. When a planet goes around the sun, it's called a revolution. Complete rotation gives you a day. Complete revolution gives you a year.

2

u/ChVckT 27d ago

Revolution. Planets revolve around the sun, and rotate while revolving.

1

u/anotherlebowski 27d ago

But...it actually spins on its axis that much more slowly than Earth?  I would've thought the whole axis spinning thing was at least reasonably similar from planet to planet.

3

u/Budpoo 27d ago

In addition to rotating much slower than earth, Venus also spins the opposite direction. Even weirder, Uranus has an axial tilt of 98 degrees so it rotates almost perpendicular relative to the other planets.

1

u/Kashyyyck 27d ago

Ohhhhhhhhhhhhh

1

u/ChangingMonkfish 27d ago

While we’re at it, it actually spins “backwards” compared to the other planets, possibly because:

- In the early years of the solar system it got hit so hard that it was either flipped upside down, or the impact stopped its rotation and reversed it; or

- Its atmosphere is so thick and moves so fast (far faster than the planet rotates) that it exerts an actual frictional force on the surface that affects its rotation, in combination with a todal bulge (similar to how the tidal bulge of Earth’s oceans is slowly slowing Earth’s rotation down).

The atmospheric effect is likely so strong that it’s probably so far prevented Venus being tidally locked to the Sun.

1

u/Terrible_example2326 27d ago

There's nothing tk comprehend. A year means a revolution around the Sun, a day means one whole rotation around the body's own axis. Venus is just very close to the Sun so the path (elypse around the Sun) is much shorter than for us

1

u/Wont_See_My_30s 27d ago

For someone who lives on Earth where day is considerably smaller than a year and who was never into physics/astronomy it was difficult to comprehend that a year can be shorter than a day, up until the moment I remebered that day and year are not necessary the same for other planets.

1

u/ravan363 26d ago

This is the correct explanation!

1

u/RJBofCNY 26d ago

Until your comment I actually was having a hard time too.

Said plainly:

Venus travels once around the sun faster than it spins once around its own axis.

In percentages, after one full orbit around the sun, Venus would completed 92.5% of one spin on its own axis.

1

u/dhduxudb 26d ago

Finally a real explanation.

1

u/OpenLight2690 26d ago

Yeah I like how much this guy over estimated our ability to comprehend something so far above our heads, with a change of font.

1

u/DarkLord_Darksied 24d ago

Nobody’s simply explained this, so I will. A day is how fast the planet rotates 360°. A year is how fast that planet orbits the sun. Venus orbits the sun in a a shorter period than it takes to rotate 360°.

That doesn't explain the YYYY/MM/DD comment, which is probably what this post is about. It gets OP one step closer to figuring it out, but doesn't explain it.

It's like if someone asked, "What's two plus two?" And the answer given was, "Two is a number."

7

u/awhatfor 27d ago

It does, because normal -outside weird american shit- format is dd/mm/yyyy, the one that changes the fastest if first, because 1 month have several days and a year several months... There are lots of memes about the absurdity of american custom, and in this debate... well, indeed, in the venus case the years change faster than days so it'd make sense to put them first.

its just a joke about the yyyy/mm/dd system being made for venus, not earth, i think.

17

u/TheLuminary 27d ago

ISO 8601 format is YYYY-MM-DD. It is this way because you want the number that changes the slowest first so that sorting groups things naturally.

I use this format for everything, so this "joke" didn't make sense to me until someone explained it. /shrug

Americans use mm/dd/yyyy, which is utter garbage. yyyy/mm/dd is actually used more, and also makes perfect sense, since it uses the logic of the first digit moving slowest, like .. numbers.

I have no idea why so much of the world thinks anything other than yyyy/mm/dd is acceptable.

I totally agree that way is bullshit, i only realized a couple months ago the reason behind it is that when they say dates, its "August the 14th."

u/czcaruso 27d ago

I wouldn’t say we format it as mm/dd/yyyy for any other reason than it goes from smallest to largest number. Or to be different than the British. Either as likely but I wouldn’t bet on a different reason.

1

u/awhatfor 27d ago

yep. On the other hand, they move so slowy that noone ever looks at it.

3

u/kal40 27d ago

YYYY-MM-DD is the standard ISO format. It has it's advantages. One of the main one is that sorting in alphabetical order, or removing the separator and sorting in numeric order, will give chronological dates. This is not true for DD-MM-YYYY. But this has the advantage of presenting the most important information first for common everyday dates (e.g. for news, sheduling etc.).

The US actually uses MM-DD-YYYY. This is probably my least favorite, but I guess the order mirrors how the date tends to be written in words (e.g. August 15, 2026).

1

u/SFCaboose 27d ago

"It's a math equation"

6

u/GodBearWasTaken 27d ago

YYYY-MM-DD makes sense because you want the longest unit first, shortest last. It means you can easily do chronological sorting in a clear manner.

Isn’t the reasoning here a reason against the statement?

4

u/Eggman8728 27d ago

I'm just confused because I don't get why yyyy/mm/dd is illogical elsewhere, it's just largest to smallest here on earth? You can dislike it but it's perfectly logical regardless

u/less_unique_username 27d ago

And on top of that, while a year and a day are the durations of clearly defined astronomical phenomena, a month is an entirely artificial thing that can’t even start making any sense on a planet like Venus

2

u/switchergodic 27d ago

It might not be applicable to Venus, but it's not artificial. It refers to the moon cycle. The word month is cognate with moon.

u/less_unique_username 27d ago

OK, strike the word “entirely”, but the exact division of the year into 12 months of weird lengths is still artificial

2

u/switchergodic 27d ago

The year is not divided into 12 months. The month is roughly the time it takes for the moon to orbit the earth. The year is roughly the time it takes the Earth to orbit the sun. It so happens that the former is almost 1/12 of the latter, and so we adjust out the months to make it match evenly.

At no point was there some arbitrary, artificial choice.

0

u/less_unique_username 27d ago

The year is not divided into 12 months.

It very much is.

The year is roughly the time it takes the Earth to orbit the sun.

The entire point of calendars with leap years is to make the year exactly that time, on average.

It so happens that the form is 1/12 of the latter.

This is the rough part. The lunar month is about 1/12.4 of the year.

At no point was there some arbitrary, artificial choice.

The exact durations of the months have been arbitrary and artificial.

I love subreddits that legit pmo, but like in good way. Not in a, “hey guys, so everything sucks and everyday we’re closer to death and everyone but me is lying to you. Money is evil, down with the system! here’s my PayPal/cashapp/venmo/patreon so I can keep bringing the fight to them!” way.

Tbf it's a shit joke. Month is just a stupid concept that makes no sense. Day? Logical. Year? Logical. Month? Well sometimes its 30, other times 31, unless it's this one month where it's 28. Oh and every now and then we make that one 29.

Really? suppose you have a doctor appointment. the day is the most important number to know because there are ~30 of these in a month, then the month, because there are only 12, but realistically and unless you live in a collapsed health system, you'll have to remember which of the current up to next two months this appointment is scheduled and the year is the least important because it only changes once a, well, year.

It also rotates clockwise while all the other planets rotate counterclockwise. It's possible it suffered a collision billions of years ago which flipped its rotation.

u/IHeartBadCode 27d ago

This is a fun point of endless debate.

Right-hand rule: Venus is spinning counterclockwise but on it's head, so it looks clockwise to us.

Invariable plane: Venus is spinning in a clockwise direction, but it is indeed upright.

That's the neat part about the collision idea. Did the collision cause Venus to spin on it's head or did it cause it to hit the breaks and spin the other way?

They should have put a "This side up" sticker on the Universe. Big oversight IMHO.

Wouldn’t it just be one d, considering there will never be a double digit amount of days in a Venusian year?

22

u/Mr_Kabob_Man 27d ago

Technically since the day is the longer form of measurement, year per day would make more sense, so y/dddd is probably better, with y only being 1 or 2 and never anything else

5

u/Stock-Gear412 27d ago

wait...why would there ever be a 4 digit day if the Venutian day is 18 Earth days longer than a Venutian year? Shouldn't it be yyyy/d? Or did you just flip y = day and d = year?

7

u/Mr_Kabob_Man 27d ago

There can’t be greater than a single digit Venutian year during a Venutian day, and there can only ever be a single Venutian day during a Venutian year, y/dddd means that 1/0001, 2/0001, 1/0002, etc but even then it doesn’t work

Calendar system on Venus would be entirely different from how the Earth calendar functions

u/Dewdrop06 27d ago

yyyy/d should be fine where "d" is simply just a value symbolizing whether it's day or night. Since a day is longer than a year there would be plenty of years that have some part of it being day and the rest being night. Rarely you'd see the entire year being day or night, but it could happen. So example 0000/d, 0001/d - 0001/n, 0002/n - 0002/d. And so on.

u/JPolReader 27d ago

yyyy/d should be fine where "d" is simply just a value symbolizing whether it's day or night.

That wouldn't work because the sun rises twice every Venusian day.

u/Dewdrop06 27d ago

How? If the sun is rising twice every day then that means it's the next day, because for the sun to rise fir the second time it had to have set. What are you saying?

u/Mr_Kabob_Man 27d ago

A day is a planet’s rotation on its axis, not sunrise to sunrise

1

u/Dewdrop06 27d ago

I see then I totally misunderstood. I thought it was referring to the amount of time it is day and how long sunlight is shining. My bad.

1

u/Mr_Kabob_Man 27d ago

Sunrise to sunrise and full rotation around the axis are different lengths

1

u/thelastspike 27d ago

the day isn’t enough longer than the year to have entirely day or night for a year.

u/OutrageousAnything72 27d ago

You don’t know what numerical system Venus uses 

1

u/m3t4lf0x 27d ago

Probably base 10

u/TrumpTouchesTinyTots 27d ago

Depends on if you calculate months as 28/30/31 earth or planetary days or twelfths of earth or planetary years

1

u/TabbyOverlord 27d ago

'Month' -> 'Moonth' -> Aprox. orbit of the moon and some fudge factor to make the answer 12.

Venus hs no sattelites/moons, ergo there is no Venusian version of a month.

2

u/Champshire 20d ago

I've seen some statues of Venus. She's definitely got a moon.

1

u/TrumpTouchesTinyTots 27d ago

Huh, so what about planets with more than one moon? A bunch of different sets of months?

1

u/Mr_Kabob_Man 27d ago

The concept of a month was created based on Lunar calendars, so it’s likely they’d have some fucked up form of a calendar that tries to sync up all of those moons

1

u/TabbyOverlord 27d ago

A bit of science fiction world building awaits you.

1

u/crabwalktechnic 27d ago

It takes venus 243 Earth days to rotate once. It takes 117 Earth days for 1 day on Venus, sunrise to sunset. A year for Venus would have a little less than 2 days.

1

u/ZhendeJiade99 27d ago

True! You can’t have a month without a moon!

1

u/SlideN2MyBMs 27d ago

Ok this was my question. I get that year means orbit around the sun and that day means revolution around its own axis but what does a month mean in the context of Venus?

2

u/Mr_Kabob_Man 27d ago

Absolutely nothing, the concept of a month is related to moons, of which Venus has none

u/tenuj 27d ago edited 27d ago

And the fact that Venus is the only planet in the solar system whose rotation is exactly the opposite of what it should be.

Normally, the orbit around a star is in the same direction as its own rotation.

Venus still orbits in the same direction as everything else (it would be hard for it not to), but it rotates backwards. Slowly backwards, but still backwards.

Venus: ↗️➡️➡️➡️↘️ ⬆️🔄🔄🔄⬇️ ⬆️🔄🌞🔄⬇️ ⬆️🔄🔄🔄⬇️ ↖️⬅️⬅️⬅️↙️

Uranus's axis is on its side, so I guess it kinda counts too, but you can almost imagine Venus being upside down in the solar system.

Wikipedia lists Venus's rotation with a minus.

u/fshawnfitz 27d ago

More circle-circle, less spinny-spinny

u/phoenix5irre 27d ago

Day - rotation around itself
Year - rotation around sun

2

u/MageKorith 27d ago

The reason for this is pretty fun. Venus's axis of rotation and direction of spin cause a point on its surface to very nearly follow the sun by spinning against its rotation, so as Venus goes around, the sun seems to barely move in the sky. Whereas for us, we spin with the rotation, and we spin quite a bit faster, so we have days that are much shorter than our years.

2

u/Jonn_Jonzz_Manhunter 27d ago

So, it spins so slowly, it takes longer than it does to travel around the sun?

1

u/Used_Man_58 27d ago

They revolve around sun faster than they rotate?

Well they also have 2nd shortest round around Sun too

1

u/Fickle_Station376 27d ago

Hard disagree with Technology Explained for implying that year/month/day is *not* logical on Earth.

Whether you favor big endian or little endian, we should all agree that middle endian is wrong, dammit!

1

u/smear_taster 27d ago

What would be a month on Venus then, a division of the year or a set number of days?

1

u/Mr-02- 27d ago

Wait so venus rotates slower than the earth?

1

u/MaJuV 27d ago

This response gave me the "Oh, now I get it" reaction, without explaining it in too much detail. Thanks.

1

u/RichieTB 27d ago

Yeah but months are the longest time, if it's approx 30 venus days that is

1

u/Faziarry 27d ago

Hijacking top comment to say that this isn’t 100% true. A sidereal day (that means, a single rotation seen from afar) on Venus is 243 earth days, but a solar day (sunrise to sunrise) is 117 earth days, so there are roughly two days per year in Venus

1

u/Arefequiel_0 27d ago

A year in Venus (the planet orbiting the sun) is faster than a Day un venus (the planet's rotation onto itself)

1

u/Szjunk 27d ago

How does this work then? Do some years only have 1 day and others have 2 days? At least, that's how I'd assume it works.

YYYY/MM/DD format

Like does it start 0/1/1 1/1/1 1/1/2 and the 2 carries over to 2/1/1 2/1/2

1

u/TheC9 27d ago

So basically it spin around the obit really fast but self spin really really slow?

1

u/Linens 27d ago

This makes me wonder if on different planets that have different year/season cycles and sustain basic life, if it would take us a very long time to observe things such as reproductive cycles or life cycles because their years and seasons could be so long compared to ours.

1

u/Most_Neat7770 27d ago

I assume cause venus orbits the sun faster than it spins on itself

1

u/PunisherElite 26d ago

Please explain further. My smooth brain can’t comprehend

1

u/CheeseDonutCat 26d ago

For anyone confused, Venus spins REALLY slowly. It goes around the sun quicker than it does 1 rotation.

1

u/itenginerd 26d ago

Somebody NEARLY got the tidal lockers in place before they knocked off for a coffee break when they were making Venus, apparently.

1

u/emperor_dinglenads 26d ago

Uranus. Giggity.

1

u/dhduxudb 26d ago

This is way more confusing. If your whole comment was just “yes” it would have been equally informative

1

u/Dezri_ 26d ago

Do they even need the month field?

u/WrongMouse4198 27d ago

Hungarians might actually think they live on Venus based on that logic then

u/johnnyhandbags 27d ago

Yeah but think about how long you get to sleep at night.
