The Founder William Herschel • Uranus was founded in 1781, by William Herschel, with the help of a telescope, He thought the planet was a star or comet at first. • It took 2 years for it to be accepted as a planet, with the help of Johann Elert Bode. • Herschel tried to name it Georgium Sidus, after King George III, but Bode suggested Uranus, from the Greek God of the sky. http: //alchetron. com/Johann-Elert-Bode-1094748 -W http: //www. messagetoeagle. com/astronomer-sir-william-herschel-announces-discovery-of-uranus-on-mar-13 -1781/

Rings ØUranus has 13 presently known rings. ØUsually a few kilometers wide ØThey are said to be composed of moons or parts of moons that were shattered by high speed impacts with an object like a comet or asteroid. Names of the rings 1986 U 2 R, 6, 5, 4, Alpha, Beta, Eta, Gamma, Delta, Lambda, Epsilon, Nu and Mu Uranus and its rings http: //pics-about-space. com/uranus-rings-nasa? p=1

http: //solarsystem. nasa. gov/planets/miranda/galleries The most interesting moon on Uranus : Miranda (or Uranus V) Close ups of Miranda ØMiranda was discovered by Gerard Kuiper in 1948 ØMiranda is the smallest moon of the major 5 with a diameter of 470 kilometers (290 miles) it is also the innermost. ØIt consists of huge fault canyons as deep as 12 miles, terraced layers and a mixture of old and young surfaces ØThe largest of the cliffs is 3 miles high, nearly three times as high as the walls of the Grand Canyon on Earth. ØMiranda's appearance can be explained by theories, but the real reason is still unknown. ØA feature on this moon called “chevron” is a series of light and dark grooves arranged in a Vshape that is shown in every picture of this moon.

Surface Conditions Ø The seasons, which last over 20 years, on Uranus don’t differ much because its so far from the sun but the average temperature is -357 degrees Fahrenheit Ø The temperature in the upper atmosphere is so cold that the methane condenses and forms a thin cloud layer. Ø It can reach speeds up to 600 km per hour. The rapid spin influences the winds. Ø Astronomers suspect that the whole planet is made of mostly water. The water should be vapor but the heat and pressure turns it into super heated liquid.

Composition and Atmosphere ØCore composition: Ø Icy Materials Ø Liquid Core ØSurface Composition: Uranus is a ice giant so it doesn’t have a surface. The planet is mostly swirling fluids. ØMinor Gases: Ø Methane Ø Traces of water Ø Ammonia ØMajor Gases: Ø Hydrogen Ø Helium

ØIt flew pass January in 1986 at a distance of around 18, 500 Km ØThis was the first time any probe had ever seen Uranus and its moons. ØAll of the information we have of Uranus is based on this exploration. The Voyager 2 flying pass Uranus
