Is Pluto a Planet?

Pluto is no longer recognized as a planet. Pluto is known as a dwarf planet. Since Pluto has become a dwarf planet, other planets have been recognized as dwarf planets as well. Pluto is very small and has few characteristics of the other planets. There are several smaller objects, similar to Pluto, orbiting the sun beyond Neptune. Eris and Ceres are the other two.
