Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.

The eight planets were created from an accumulation of most of the material that remained in their vicinity. They are the dominant bodies in their regions of space. This view is the one officially adopted by the International Astronomical Union.
