Uranus is the third largest planet from the sun. It was first discovered by accident in 1781 with a telescope by William Herschel. On January, 1986 Voyager 2 flew by Uranus and updated information that we didn’t have. It discovered that Uranus had two more moons and rings.

Scientists think the center of Uranus is an extremely hot inner core, followed by a layer of diamonds. Next comes a layer of mantle of ice and slush. The next layer is made up of an ocean of hydrogen and then an atmosphere. The final layer around Uranus is smog. Uranus is made of two gases, hydrogen and helium. The gases give it its green color. Air on Uranus’s dark side glows and is called "Electro glow".

Scientists think the Temperature under the clouds are 216 degrees Celsius. There may be water under the clouds. But the surface of the planet is 353 degrees Fahrenheit or 220 degrees Celsius.

Uranus has 15 moon all together. The moons are made of rock, mountains, craters, fissure and ice because it was hit by a comet. I’n going to tall you a little bit about the big moons.

Oberon is the biggest moon out of all 15 moons. Oberons made of many diffrent thing. There names are craters, and mountions. Oberon has a diameter of 1,000 km.

Titania is made of two ting. Trintses and cliffs. Its diameter of it is 1,000 km.

Umbriel is old, dark, and it has big craters on its surface. It diameter of it is 700 km.

Ariel is just like the grand canyon but it has a lot of canyons on it surface. It has valleys to just like the Earth. It diameter of it is 700 km.

Meranda is the last moon I’m going to tell you about because that is all the information I got on the biggest moons.

Meranda is the smallest moon out of all the moons I’ve told you about. It diameter of it is 300 km.

Uranus has 10 rings around it surface.

It’s rings are very faint, so faint that there almost invisible. Scientists thank that there still are some rings forming. In 1986 voyager 2 flow by Uranus and took photographed of thin dark rings around Uranus’s surface. The whole ring system is very thin. The rings are made out of big boulders more than a meter wide. These rings do not shine. But they are made of black rocks that look like coal.
