Voyager 2 used Saturn's gravity to slingshot it on to Uranus, a planet that's mostly water, ammonia and methane.
This planet's pole points to the Sun, which may be the result of some vast cosmic collision in the past.
Uranus's large moon Miranda is named after one of Shakespeare's characters, but it too shows the scars of a very non-poetic past!
Uranus was discovered on March 13, 1781 by British astronomer Sir William Herschel. The planet had been observed as early as 1690, but it was believed to be another star.
