Why Dwarf Planets?
• There are 3 Dwarf Planets in our Solar System; Pluto,
Eris (found in the Kupier Belt) and a very large asteroid
called Ceres.
• What is a Planet?
– In 2006 the International Astronomical Union define
a planet as an object that orbits the sun with
sufficient mass and gravity.

“neighborhood” and they are not a moon(satellite)
