Under the 'has cleared its orbital neighborhood' and 'fuses hydrogen into helium' definitions, thanks to human activities Earth technically no longer qualifies as a planet but DOES count as a star.

what is the name for things in orbits that aren't asteroids ?

Satellite.

Can also be broken down to natural and artificial satellites, but natural has extra requirements than just being naturally occurring.

Debris?

[–] [email protected] 1 points 4 days ago

I mean including things like planets, an umbrella term that planets are always on

it doesn't sound to me like you could just say a planet is debris although I do think the formation of the moon could technically be space debris so maybe other larger celestial objects may have originated as such

I'm a computer person. not a space or physics person so forgive my lack of correct terminology
