As a result of the Pluto debate, astronomers realized that there was no clear definition of the word planet. There were many ideas about what a planet was and was not. Consequently, a group of astronomers from the International Astronomical Union got together and created a definition on which they could all agree. The definition states that a planet is a body that 1) moves around the sun, 2) is large enough for its own gravity to make it round, and 3) has "cleared [the] neighborhood" around its orbit of smaller objects. Under this new definition, the scientists decided that Pluto was too small to be a planet, and they changed its status to "dwarf planet.
