Uranus

Showing that you shouldn't draw conclusions based on too few facts, new NASA research suggests that a decades-old view of Uranus as an unusually cold planet isn't true, but that it does actually generate its own heat as other worlds do.

If you've been wondering how long the day on Uranus is, you probably need to get out more. But if you have, you'll be interested to know that observations by the Hubble Space Telescope have shown that it's 28 seconds longer than previously thought.
