Uranus is an extremely unique and funny 'blue-green ice giant' among the eight planets. Its most famous, hilarious feature is that it rotates in space almost 'completely lying down sideways on its flank'! While other planets spin upright like tops, Uranus rolls along its orbit like a round ball rolling forward. Scientists guess that a very long time ago, it might have been accidentally slammed hard by a super massive space object, tilting its body completely. Uranus is encircled by a faint small ring system and has 27 happy little moons. Because it is so incredibly far from Grandpa Sun, taking one full lap around the sun equals a whopping 84 years on Earth! The methane gas inside its belly absorbs red light, which is why it reflects such a beautiful blue-green coat. In human history, only the incredible 'Voyager 2' probe has ever flown close to visit it and send back precious data.
