It is located twice as far from the Sun as the Saturn which is the closest planet in from Saturn. Uranus is a gas giant with a possible rocky core but surrounding core is an extremely hostile gassy atmosphere, one in which it would be a struggle to get anything into to investigate. The first time Uranus was visited by a space probe was in 1986 by the Voyager 2 space probe which flew past on its way out of the solar system.
Whilst all the gas giants have a ring, Saturn has the most prominent rings followed by Uranus. It was not until 1977 that the rings were discovered when astronomers were observing the planet crossing the path of a star. The astronomers noticed the star blinked before Uranus has blocked the star, thus they realised the blinking was caused by the planet having rings.
Uranus is unique amongst all the planets in The Solar System in that it rotates on its side. This is probably caused by a collision with another body that knocked it on its side. Whereas on Earth, the planet rotates east to west, the planet rotates south to north in comparison to our own planet.
The planet was the first to be discovered since ancient times, everyone believed that the solar system stopped at Saturn. The planet was discovered by Sir William Herschel, a German Born Astronomer who moved to United Kingdom and discovered Uranus. The planet was discovered on March 13th, 1781 by Herschel using a telescope because it was far it couldn`t easily be spotted by the naked eye which the other planets had been discovered. Herschel had wanted to called it George`s Star but that got overruled and became Uranus. The choice of Uranus was because Saturn was the father of Jupiter and so to follow on, Uranus is the father of the Greek God Saturn. The planets name became the inspiration for the newly discovered element Uranium.
