Answer 2

@lncognlto do u know what it is

Answer 3

I have a suspicion I do... It's unlikely that a planet is going to be found in the Kuiper belt, ad that is made of asteroids, and a planet has enough gravity to clear its orbit of other particles. A planet will never be a moon, it will orbit the sun, and it's orbit will be circular, and probably long. Based on this, which do you think it is? :)

Answer 4

a?
