What is the ninth planet in our solar system?

1 Answer

Pluto had been considered the ninth planet in our solar system since its discovery in 1930, but in 2006 the International Astronomical Union changed the criteria for a planet, relegating Pluto to the designation of "dwarf planet," and leaving our solar system without a ninth planet.
