Weirdly Wonderful Uranus Facts for Kids
Uranus has only been visited by one spacecraft.
NASA's Voyager 2 is the only spacecraft to have visited Uranus. On 24 January 1986, the spacecraft—which had been launched about 8 years earlier, having already visited Jupiter and Saturn— passed within about 81,500 km of the clouds on Uranus' surface. Voyager 2 then continued on to visit Neptune some 2 years later.
Uranus orbits the sun on its side.
With the exception of Venus, all the solar system planets rotate on their axes from west to east. Although they are all slightly tilted, Uranus is tilted to such an extreme degree that it's effectively rotating on its side.
