The+Stunning+Uranus!!

__**You are now on the planet Uranus!**__  First you should know the basic information of Uranus, It’s quite simple. Uranus is the 3 rd largest planet in our solar system. It is one of the outer planets, so its 1,784 million miles away from the sun, which makes it the 7th planet away from the sun. The rotation period of Uranus is 18 hours. The rotation period means how long it takes for Uranus to complete one orbit around the sun. The revolution period takes Uranus 84 years. Uranus has 27 moons; the biggest of all of them is Titania. It is about half the size of Earth’s moon. Uranus’ atmosphere consists of hydrogen, helium, and methane(kidsastromony).

Now that you know some of the basic information you should learn a little about the history. The person who discovered Uranus was a man named William Herschel. He discovered it on March 13, 1781. William Herschel was a British astronomer. He made over 2,500 discoveries most of them were deep sky objects. He also helped build and improve a reflecting telescope. The planet Uranus was named after the Greek God of the sky. Every planet has a symbol, Uranus’ planet symbol looks like this…(nineplanets).

The physical properties of Uranus are very important to know about also. One thing that is important to know is that the mass is 8.68x1025 Kg, which is the same as 14.5 Earths. The temperatures are very extreme on Uranus they reach a chilling -328o F. With a diameter of 32,000 miles it is an astonishing 4 times the diameter of Earth. The escape velocity of Uranus is 21.3 kg/s. The average density is 1,270 kg/m3. On Uranus there is no solid surface, the whole planet consists of gases and liquids. The atmosphere composition is made of hydrogen, 83% helium, 15% and methane, 2%. The first layer of Uranus is hydrogen, helium, and methane. The second layer is made out of liquid hydrogen. The third layer is icy water, ammonia, and methane. Finally the core is made out of molten rock(nasm).

There are many unique features of Uranus. One thing many people don’t know about Uranus is the fact that it has 11 rings. The ten outer rings are dark and thin. The 11th ring is inside the other 10 and it is very broad. Uranus is rotating on its axis sideways; this may be because of a collision with another planet. Scientists still are not 100% sure why it does. The sunlight that reflects through the methane layers of gas absorbs the reddish yellow color and makes us see it as a bluish green color(exploratorium).



There has not been much planet exploration due to the extreme temperatures. The Voyager 2 probe was launched on August 20, 1977. It passed Uranus in January, 1986. It discovered 10 new moons and 2 new rings(nasa).

There are many interesting facts about Uranus. I was born on October 30, 1995. My next birthday on Uranus would be November 3, 2079. For example if you weighted 110 pounds on Earth you would weigh 97.7 pounds, and if you weighted 170 pounds on Earth you would now weigh 151.1 pounds on Uranus. If you had to make a model of the solar system with the sun being 615 millimeters you would have to make Uranus 20.7 millimeters(weight/age/solar_system).
