Answer:

Planet X is closer to the sun then Planet Y, which makes it a dwarf planet. Planet Y is also too small to be an ACTUAL planet.

Explanation:

I know this answer because I remember how Pluto became a dwarf planet, because it was to small, was far away, and had a weird orbit. You're welcome!
