Ur orbit around the Sun in 84 earth years. It completes its turn around itself in 17 hours and 14 minutes. This means there are about 43,000 days in 1 uranian year.
The distance between Uranus and Neptune is 1.6 billion km. Uranus was discovered in 1781. Uranus has 13 known rings which are hard to see from earth.
This planet can be seen with the naked eye under perfect conditions. Some evidence suggests that this planet was catalogued as a star (34 Tauri) before its confirmed discovery.
Uranus is named after the Greek god Uranus, who was a god of sky.

Moons
Uranus has 27 known moons. The names for these moons are chosen from characters from the works of Shakespeare and Alexander Pope.. There are also violent storms on the surface with winds that blow at 160 miles per hour. Scientists are studying the clouds to try and understand the storms on the planet.
Rings
The planet Uranus has a system made of 13 rings between the more extensive set around Saturn and the simpler systems around Jupiter and Neptune. The rings of Uranus were discovered in 1977. More than 200 years ago, William Herschel also reported observing rings, but modern astronomers do not believe that he saw them, because they are very dark and faint. Two additional rings were discovered in 1986 in images taken by the Voyager 2, and two outer rings were found in 2003–2005 by the Hubble Space Telescope. The rings are probably mainly composed of water.
Origins. A number of dust bands between the rings were observed in forward-scattering geometry by Voyager 2. All rings of Uranus show azimuthal brightness variations.
The rings are made of an extremely dark material. The rings are slightly red in the ultraviolet and visible parts of the spectrum and grey in near-infrared..
. Its orbital elements were first calculated in 1783 by Pierre-Simon Laplace..
