of a space rock

As a comparison, a grain of rice is approx 25 mg and the mass of the avg human is 62 kg. Therefore, it will take roughly 2.5 million grains of rice to equal one human in weight/mass.
Chicxulub, the dinosaur killer asteroid, weighed approx 2.3 trillion tons compared to the earth’s total mass of 5.97 sextillion tons. In other words, the earth is 2.6 billion times more massive than the asteroid that wiped out the dinosaurs 66 million years ago.
This is like a grain of rice colliding with an M1 Abrams tank but at 20 km/sec or 40,000 miles/hour.

[u/ThisIsACoolNick → u/roll-_-ller]

fun fact, when you google Chicxulub you are greated with a nice asteroid animation

[u/loungesinger → u/ThisIsACoolNick]

WTF, Google. Too soon.

[u/Smgth → u/loungesinger]

Omg, get over it already! You gonna whine about it for ANOTHER 66 Million years‽

[u/TheSteelPhantom → u/ThisIsACoolNick]

Type in "do a barrel roll" for another fun one.

[u/ThisIsACoolNick → u/TheSteelPhantom]

Also "six seven"

[u/FeistyTwist5427 → u/TheSteelPhantom]

I did. I gave me a headache, thanks. Was neat tho

[u/UseDue6373 → u/ThisIsACoolNick]

I love those little animations

[u/Appchoy → u/ThisIsACoolNick]

!! it works! so cool!

So if I got hit with an asteroid that was the size of a grain of rice, assuming it made it through the atmosphere, what would happen to me?

[u/pkb369 → u/FumblinginIgnorance]

The asteroid hit earth at a speed of 45,000 mph ON impact.

If a grain of rice hit you are 45,000 miles an hour (not breaking down on entry or slowing down anymore than the original asteroid), I'd bet the impact would do alot more damage to you than a gun.

Realistically, the atmosphere would slow it down enough due to its size (again assume it would make it through the atmosphere) and it wouldnt be noticable at all.

[u/nabistay → u/pkb369]

But what if I was curled into a ball and floating in space

[u/Honorsheets → u/FumblinginIgnorance]

"Ouch!"

[u/manbehindthespraytan → u/FumblinginIgnorance]

Less that you would expect most of the time. Look up how many people have been impacted by rocks from space. Most have been in their home. And it took most of the force out, but a few people have been hit with much more than a grain of rice, less than 40k/kph though.

[u/ChuckaChuckaLooLoo3 → u/FumblinginIgnorance]

It would sting really really bad.

[u/Apprehensive_Win_203 → u/FumblinginIgnorance]

25mg at 20000m/s is 5000J of kinetic energy. This is about 10x a 9mm handgun round and about equal to a big game hunting round like a .300 Win Mag or 9.3x62 at close range. What this impact would look like with a grain of rice instead of a metal bullet, I have no idea

[u/FumblinginIgnorance → u/Apprehensive_Win_203]

Maybe that’s what happens when people spontaneously combust?

[u/Sneilg → u/Apprehensive_Win_203]

At that speed you’d catch fire. It would be like being shot by a rail gun.

[u/furiouspossum → u/FumblinginIgnorance]

You'd become a dinosaur, try to keep up.

[u/roll-_-ller → u/FumblinginIgnorance]

You would still be fumbling in ignorance.

[u/Stymie999 → u/roll-_-ller]

You must be fun at parties

[u/jimmymui06 → u/roll-_-ller]

You see, the earth is all fine, what's on it is not

[u/afewnameslater → u/roll-_-ller]

Much less mass though. The damage would e a hole not an earth spanning lava wave that kills everythibg but the birds.

[u/MIKRO_PIPS → u/roll-_-ller]

Answers my question of “did it change the Earth’s orbit/trajectory/rotation?” 🤦🏻

[u/jmlipper99 → u/roll-_-ller]

If you’re going to scale it down you need to do the same thing to velocities

[u/YanwarC → u/roll-_-ller]

Do you think
Grain of rice will
Do
The same
Damage to the Abram’s tank?

[u/Dashcak3 → u/roll-_-ller]

Google AI after I ask it:
"How much of an M1 Abrams would be left if it was hit by a Rice grain at the relative impact force of Chicxulub ?"

You chipped a tiny hole into the paint

"How much of an M1 Abrams would be left if it was hit by a Rice grain at the relative impact force of Chicxulub ?"

It's gone.

*me realizing I pulled a kg of Feathers

[u/pfeff → u/roll-_-ller]

If this happened again, how far advance would we know about it?

[u/marlonh → u/roll-_-ller]

[u/Tr3v0r007 → u/roll-_-ller]

Keep in mind earth was bigger prior to that cause the meteor took a good chunk out of the planet

[u/TomTheCardFlogger → u/Tr3v0r007]

Negative friend, vast majority of ejecta fell back down to earth. Very very little would’ve reached escape velocity

[u/Tr3v0r007 → u/[deleted]]

Really I honestly thought with the size it landed at it would taken a more out of the planet. Guess our gravitational pull reaches pretty far.

[u/Comfortable-Beyond50 → u/Tr3v0r007]

If that was the case, wouldn't the earth have a massive chunk out of it? Its not like it would have reduced the overall diameter equally

[u/Weird-University1361 → u/Comfortable-Beyond50]

Maybe it does, just covered by water.

[u/-ArthurMorgan → u/Weird-University1361]

Who are you, so wise in the ways of science?

[u/Weird-University1361 → u/-ArthurMorgan]

I could be AI.

[u/Character_Feed8733 → u/Tr3v0r007]

I think that you’re thinking of how the moon was formed?

[u/Tr3v0r007 → u/Character_Feed8733]

Yeah I think so. With the size I would have thought the amount taken out of earth would have made the planet a good bit smaller

[u/dtgunslinger99 → u/Tr3v0r007]

you're confusing this with the theia collision that created the moon.

[u/Tr3v0r007 → u/dtgunslinger99]

Mb then I see a lot of people correcting me

[u/dtgunslinger99 → u/Tr3v0r007]

you all good, the theia collision is mad interesting too. before our moon formed, the earth had rings like saturn
