Uranus was initially discovered by William Herschel on March 13, 1781.
There has only been one fly by of Uranus completed by the NASA Voyager 2 Spacecraft which discovered ocean sized body of water, 10 new moons, and 2 new rings. The fly by also discovered the oddly titled magnetic field that is stronger than Saturn’s.
Uranus has a tilt degree of 99 which creates an extended period of darkness and light on its northern poles. This time period is 42 years of darkness then 42 years of light. The reason for this is the 99 degree tilt which in turn also effects the planet’s orbit.
For Uranus the rotation of the planet is the opposite of Earth’s, the sun also rises in the south and sets in the north unlike the Earth’s east to west.
Uranus’s rings are a very recent discovery, as scientists first observed them by 1977. Saturn was thought to be surrounded by five narrow rings, named Alpha, Beta, Gamma, Delta and Epsilon, in order of increasing distance from the planet. However scientists have now observed 13 rings around Uranus, named 1986U2R, 6, 5, 4, Alpha, Beta, Eta, Gamma, Delta, Lambda, Epsilon, Nu and Mu. Uranus’s larger rings are surrounded by belts of fine dust.
Uranus has no solid surface, and is a gas giant. Its atmosphere is composed primarily of hydrogen and helium, with a small amount of methane and traces of water and ammonia. Most of the mass of Uranus is contained in an extended liquid core consisting primarily of icy materials like water, methane, and ammonia.
