Congratulations!  Did you realize it was Uranus? The first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.  Uranus is made of water, methane, and ammonia fluids above a small rocky center. Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane.

The methane makes Uranus blue. Uranus orbits our Sun at a distance of about 1.8 billion miles (2.9 billion kilometers) or 20AU.

Uranus takes about 17 hours to rotate once (a Uranian day), and about 84 Earth years to complete an orbit of the Sun (a Uranian year). Uranus has 27 known moons, and they are named after characters from the works of William Shakespeare and Alexander Pope. Uranus has 13 known rings. The inner rings are narrow and dark and the outer rings are brightly colored.

A really cool fact:  Like Venus, Uranus rotates east to west. But Uranus is unique in that it rotates on its side.

Figure this: Multiply your weight by .92 to find out how much you would weigh if you could stand on Uranus.

Time to move on, you are almost to the last of our planets. We will definitely be a long way from the Sun.  Think about how much gravity the Sun has in order to have an influence this far.  Off you go.
