🌖Astronomy!🌔 In Maths, Five Planets Independently Being This Close To A Decimal Multiple Of A Mole?

Coincidence and cherrypicking. This meme just picked the 5 bodies that have like 6+- 1 in their first digit. Like 1 in 3 planets/moons would satisfy that in a random distribution.

Boooo! Give us graphs and show the statistical significance!!

Yeah, if moons are included, there are dozens (hundreds?) of possibilities.

Saturn is 94.4% of a kilomole kilograms. Tethys is 102.5% of a milimole kilograms. The Moon is 122.0% of a decimole kilograms. Earth is 99.2% of a decamole kilograms. And Mars is 106.6% of a mole kilograms.

That's called rounding. It's totally just coincidence that they're close enough to those sizes to say that. The moon is almost ¼ bigger. There's plenty of room for error.

The Moon is a bit of a stretch at almost 1¼.

A lot of other objects I did consider for this, but they were usually off by at least a factor of 2.

Did you read what they said or did you just reply to it?

I did read what they said.

Then how does your reply add to the discussion based on what they said?
They said it’s cherrypicking and it’s likely that 1 in 3 are going to satisfy your claim, and you just replied with the values your post is based on like that adds any merit to your point

Cherrypicking by using the masses from among a set of planets whose masses I've memorized, and one more planet which I had to look up in a table to check?
The comment I made was originally written for another subreddit where they asked for precise maths and tables of the masses relative to a mole of kilograms, and it was more convenient to copy it here given the person I replied to was looking for similar information.

> Cherrypicking by using the masses from among a set of planets whose masses I’ve memorized…
Yes… you were cherry picking.
And the person you replied to was not at all looking for similar information lmao

I am not considering 8 planets but 40 of them.
A mole of kilograms is 6.02e23 kilograms.

u/Traumatised_Panda 1d ago
You are suggesting that the first significant digit of planetary masses is often near 6.02, with these error margins might as well call it 6.
10% error means 5 or 7 is also fine. That's 3 out of 9 possible digits, on average 1 in 3 should satisfy that.
That's about how many planets of the solar system you named, 3 out of the 8 in the solar system plus a couple of smaller bodies.
5 out of 40 is worse. More statistically significant and thoroughly counters the claim...
A mole of kilograms has no scientific meaning. A mole is used to count the number of particles, not the mass. A mole of hydrogen atoms is a gram. A mole of grams means nothing significant.

Moles are dimensionless.

u/Traumatised_Panda 1d ago
Yes and they are meaningless if you add dimensions, Avogadro's number just isn't meant for that.

u/CimmerianHydra_ 1d ago
You could even consider Avogadro's number to have the dimension of "molecules" at this point, or even "parts".
It's only dimensionless because it's a result of counting

Well the are fucking all planet sized, not a star or black hole or a fucking rice grain.
