is the seventh planet from the sun in the solar system. It has the third largest mass in the solar system. It was William Herschel who discovered Uranus in 1781. In two years William thought it was a star or a comet. But then Uranus was accepted as a planet because of Johann Elert Bode’s observations. William wanted the planet to be called Georgium Sidus because of the king George III. But the planet was called Uranus after the Greek god of sky. It takes Uranus 17 hours and 14 minutes to to rotate 1 time and it takes 84 earth years to spin around the sun 1 time. It has got 27 moons and they are divided into three different groups: thirteen inner moons, five major moons and nine irregular moons. The moons are named after characters …show more content…

That means it will take a very long time for the sunlight to travel to Uranus ( It takes 2 hours and 40 minutes). The surface gravity on Uranus is around 86% so if you weigt 100 kg you will have a weight of 86 kg. It is surrounded by wire-like strings of dark ice particles. In Uranus atmosphere there have’nt been so many cloud seen ( just a few white clouds). Uranus has got a temperature around -224°C. The materials, pressures and temperature are too extreme for humans to live at Uranus. There is only one spacecraft that have visited Uranus because the distance between Uranus and Earth is 3 billion kilometers. The spacecraft that came to Uranus is called NASA’s Voyager 2. The spacecraft found out information about the moon and the rings around Uranus all of that in just 6 hours. It also discovered 10 new moons and that Uranus has got a stronger magnetic field then saturn. Uranus is called the ice giant because it is made up of frozen water (ice) methane and ammonia. Uranus can hit the coldest temperature of any planets in the solar system. Neptune is average more colder but Uranus can sometimes be really …show more content…

It spins around itself in 16 hours and 6 mins (So one day is 16 hours and 6 minutes). The distance between Earth and Neptune is around 4.4 billion kilometer. Because of the long distance Neptune is invisible to the naked eye. The gravity on Neptune is around 110% of the gravity on Earth so if you weigh 100 kg you will have a weight of 110 kg on Neptune. Neptune has 17 times the as of Earth. In Neptune it can get really windy. A wind can be up to 9 times stronger than earth’s winds. The temperature on Neptune is -214
