The average distance from the Sun to Neptune is about 30 AU. That's 30 times the distance from Sun to Earth. This means that the amount of solar energy Neptune gets, per square meter, is 1/900 (1 divided by 30 squared) that of Earth.

Neptune is extremely cold because it is very far from the sun. Neptune, however, generates some of its own heat, unlike Uranus, which has a similar composition.
