The discovery of other similar objects to Pluto in more recent years has meant that astronomers either had to keep adding planets to the list, or we had to redefine what a planet actually was. In 2006, a new definition for a planet was established. It had to be approximately round, it had to orbit the sun and it had to have cleared its neighbourhood of all other objects - so that at that distance from the sun, there were no other sizable bodies. Pluto is not large enough to have done the latter, while all other remaining planets have, so it was downgraded to a dwarf planet. There are now eight planets recognised and five Dawrf planets, of which Pluto is one.

Is charon a dwarf planet?
No.It is a satellite (moon) of Pluto, which itself was declared a "Dwarf Planet" at the International Astronomical Union (IAU) Symposium in 2006.Pluto is very small - only 2/3rds the size of Earth's moon. Charon is 1/2 that size - which is large enough that the IAU would have faced calling Pluto-Charon a "Double Planet" if they had decided to call Pluto one.However, IAU's decision was based upon the fact that there are MANY objects in similar orbits to Pluto's (some even larger than Pluto itself, such as Eris), and we would have ended up listing dozens (possibly hundreds) of objects as "Planets"No. Charon is not a planet; it is a moon of the dwarf planet Pluto.
