Be like Pluto.

The problem with recognizing Pluto is that Eris, Haumea, Makemake, Gonggong, Quaoar, Sedna, Ceres, Orcus, and perhaps also Salacia also should probably be included, and that makes for a nightmare of a mnemonic. As we all know, classification is decided on mnemonic plausibility.

Pluto was not the first 9th planet. Then again we were up to 13(?) at one point.
Pluto was
Because Pluto is the 9th planet?
How are you counting?

What's the problem with having many many planets in our solar system? You don't have to remember them all.
We also have many many stars in our galaxy. We don't have to know their names for them to still be stars.

You don't ever see people calling for Ceres to be proclaimed planet, all they care about is Pluto.

You also can't find a good problem with this, can you?

Cool. Can you name all planets in the Solar System, in the correct order?

I can't.

I can't.
Yeah. To answer your question, I see that as the problem. If you don't, well, we'll have to agree to disagree on that one.

wrote last edited by [email protected]Do you know why you apply this logic to planets, but not stars?
I also can't name all the planets outside of our solar system, but that seems to be less of an issue for you.

"Educated"
We eliminated Earth by accident.
Of course we didn't. The International Earth-Destruction Advisory Board would have reported that...
Shit.

Pluto and the others are planets even without including them all in the mnemonic. The mnemonic is for the first 9 planets, just like you only remember the first few digits of pi.
Ceres is between Mars and Jupiter.

What are your thoughts on Ceres?
There's not clearing your orbit, and then there's whatever Ceres is doing.
Typical lazy Beltalowda.

Planet has never been very well delineated. The Sun was a "planet". Ceres was a "planet".
When we find enough things to break up the classification, we make a new classification. Like "asteroid" or "dwarf planet" or "gas giant".
I don't think the sun is in orbit around the sun.

Every planet ellipses.
Not to the degree of Pluto, which also can't be bothered to orbit in the solar plane

OK, how about Eris

Possibly over 100.

The meme does get at an important point though -
Our classifications of things have no impact on the things themselves. They are descriptive, not prescriptive. We create the category “planet” as a useful tool for referring to certain categories of astronomical objects. These objects would exist whether we had words for them are not.
There are patterns in what the word “planet” describes that would also be shared, whether all of those things were called “planets” are not, but the words themselves are just useful shorthands depending on the context that we use them in. The map is not the territory; the referent is not the reference.
(This is also about sex/gender.)

Neither can Eris, but it's also not a planet probably

So whatever hypothetical density constitutes an atmosphere becomes the arbitrary line in the sand.
Similar to the arbitrarily defined density of other stuff in the same orbit. We need to draw lines somewhere to impose categories on nature.
