Pluto has always had the 'honour' of being the coldest planet with an average temperature between -360 to -400 degrees Fahrenheit. This is because it is so far away from the sun: it is over 40 times further from the sun than planet Earth.
Pluto also has no internal heat source and it even orbits in a ring of ice debris.
However, since September 2006, Pluto has been downgraded. It is no longer a 'proper' planet ie there used to be 9 planets in the solar system, of which Pluto was one. Now there are only eight planets and Pluto has been re-classified as a dwarf planet.
Its nearest neighbour, Neptune is also a considerable distance from the sun about 1.5 billion kms. But Neptune has an internal heat source which means that it has a temperature similar to Uranus, even though it is further away from the sun.
