Twin planets. Caron and Plato. Downgraded to dwarves because NDG sucks milky ways.

He might suck, but you know it wasn't his decision right?

Yeah, but it's fun to blame him. He was vocally parading the news and using it, as usual, for self promotion. So I let him have it.

Charon is still a moon, nobody upgraded it to dwarf planet.

[–] [email protected] 2 points 5 months ago

That seems terribly unfair. Downgrades but no upgrades?

I thought for an object to be a satellite it's orbital point had to be located inside the body of the other entity.

There's currently no formal definition requiring that. By that definition, none of Pluto's five moons would be moons, since they all orbit the same barycenter.

There's a whole discussion about it here and it looks like it might be reconsidered in the future https://en.wikipedia.org/wiki/Charon_(moon)#Classification
