Best Answer

Contrary to popular belief, new evidence has shown that Neptune, despite being the furthest (8th) planet from the sun, is actually not the coldest.

Neptune has an exposed core of molten ammonia and superheated methane. Because the planet has no defined surface, there is nothing preventing the heat escaping the core. Therefore, it slightly warms up the planet, though, not enough to stop it being freezing.

The coldest planet is actually the 7th planet in the solar system, Uranus. The core is not as exposed as Neptune's, so less heat escapes to warm the planet.
