Uranus was discovered by William Herschel in 1781. Uranus was the first planet discovered in over 2000 years and therefore was a huge event in the 18th century. Uranus is seventh planet from the Sun and more than 19 times further from the Sun than Earth (19.2 A.U.). At that distance it takes light almost 2.66 hours to get to Uranus from the Sun. Uranus is another of the Jovian planets and also has a ring system. Uranus is unique in the fact that it experienced a collision so massive that it was left ajar with an axial tilt of almost 98° that produces a retrograde rotation on its axis. A year on Uranus is equal to 84 Earth years and a day on Uranus is about 17.2 hours or about (- 0.72 Days)

Uranus was named after a Greco-Roman mythological god of the Titans. Although Uranus is far away it can be observed with the naked eye when sky conditions are excellent and can be observed easily with a small 6 inch telescope. Uranus has a featureless atmosphere with enough methane gas to absorb red light and reflect back to Earth a pale bluish color. Uranus has a ring system that was first discovered from Earth. Uranus has 27 known moons.
