The IAU (International Astrology University) came up with three criteria that an object must meet in order to be considered a planet:
- The object must orbit the sun.
- The object must have strong enough gravity to pull itself into a nearly spherical shape
- The object must be able to clear its neighborhood of debris.
Pluto fails the third criterion and so is classified as a dwarf planet.
