Pluto is not a planet

Answer 1

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.

Answer 2

Pluto is not a planet because it is not the dominant object in the region around its orbit.

So, it fails to satisfy this criterion and is not classed as a planet, by the definition established in 2006.

Answer 3

Pluto is now considered to be a dwarf planet along with Ceres, Eris, Haumea and Makemake.

Answer 4
