It was discovered, made a planet, and then kicked out the club in that time.

If you think 2020 was bad, wait until you hear about Pluto's year... the American civil war, ww1, ww2, the great depression, the moon landing... the American civil war...

It's been a really rough year for Pluto. Let's all wish it good luck next year (when humans are probably dead).

It was the runt of the litter and didn't survive full planet hood.

Fine I'll look it up. Discovered 1930, so that makes a Pluto year 248 Earth years.

How can we even know it's a planet when we haven't observed a single orbit, yet?
Maybe it's just a really big comet.

We've observed enough of its orbit to know what shape it is.

It's not really big. There are multiple Pluto like planetoids. Also there is a hunk of rock in the asteroid belt youcould name a planet.

Ceres is more than a third of the mass of the asteroid belt. It's at least an order of magnitude bigger than anything else in its orbit. It's hardly a hunk of rock

There's also not that much rock, only 73% of the mass. The rest is ice and mud, with half it's volume being water in some form.

By measuring how fast it's moving and where it is you can find the orbit

Dwarf planet is a planet!

IAU names aren't the best, "planet" should be major planet.

Temporary planet designation for its birthday!!!! Time for Christmas spirit, y'all!

On that note, Santa and all his elves will have drowned from North pole melting long before then.
