Constraints P2243 and P2233

Comets like Comet Lulin (Q477976) should not have properties like apoapsis (P2243) and semi-major axis of an orbit (P2233) (or they should be "novalue"). But I guess it is better to make exceptions for them, than removing these Constraints. -- Innocent bystander (talk) 11:49, 20 October 2015 (UTC)

Parent astronomical body

I don't think it should be needed to add the parent astronomical body (P397) property, at least when we talk about man made satellites. Since doing that requires to add the child astronomical body (P398) property to Earth (Q2), I found it rather impractical since we would need to that to 4000 satellites that are currently orbiting the Earth.--BugWarp (talk) 19:31, 24 November 2019 (UTC)
