Pluto was discovered in 1930 and originally called a planet. In 2006, Pluto was re-classified to be a dwarf planet due to the discovery of a number of similar rocky, icy bodies in the solar system. To avoid increasing the number of planets dramatically, Pluto and similar bodies were re-classified.
What else can I help you with?
Is there anything special about Pluto?
Pluto is unique in our solar system as the only dwarf planet. It has a highly elliptical orbit that brings it closer to the Sun than Neptune at times. Pluto is also known for its large moon, Charon, which is so large in comparison that they orbit each other, creating a binary system.
When did they stop calling Pluto a planet?
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.
