It is planet Pluto.

______________________

There are five "dwarf planets" in our solar system, as of August 2010. There are certainly dozens or hundreds more in the distant parts of our solar systems, but our telescopes are not yet good enough to see them.

Pluto was considered a planet until the International Astronomical Union (IAU) reclassified it.

Ceres was an asteroid before the IAU reclassified it.

The Kuiper Belt Objects later named Eris, Haumea and Makemake were all considered to be candidates for being named the "Tenth Planet" until the IAU came out with its definition of "planet". In fact, it was the discovery of the dwarf planet Eris, originally called "Xena", that caused the IAU to finally come up with a formal definition of "planet". All three of these objects are now considered to be "dwarf planets".

There are several other large asteroids that probably deserve "dwarf planet" status as well; Vesta, certainly, and Pallas, and perhaps a few others.
