WHY PLUTO IS NO A PLANET??
~ Until recently, Pluto was the ninth planet from the Sun. It was also the smallest planet. Poor Pluto. Just how did he get "kicked out" of our family of planets?
And who are his "real" family members? Astronomers have already named three other objects in the solar system that are about the same small size as Pluto. They are Ceres [SEAR-ees], Makemake (MAH-kee-MAH-kee], and Eris (AIR-iss]. These objects, along with Pluto, are much smaller than the "other" planets.

Astronomers have put these objects into a new family called dwarf planets.
