  1. 1. Uranus
  2. 2. The size of Uranus <ul><li>The diameter of Uranus is 31,765 miles or 51,118 kilometers which is about four times the diameter of Earth and Uranus is the third largest planet in the solar system. </li></ul>
  3. 3. How far is Uranus from the sun <ul><li>Uranus is an average distance of 1,783,939,400 miles or 2,870,972,200 kilometers from the sun. The closest Uranus gets to the sun is 1,699,800,000 miles or 2,735,560,000 kilometers. </li></ul>
  4. 4. How many moons <ul><li>Uranus has 27 moons that we know of. The five large moons are called Miranda, Ariel, Umbriel, Titania, and Oberon. Titania is the largest moon of Uranus and it is covered with small craters, a few large craters, and very rough rocks. </li></ul>
  5. 5. Rings <ul><li>Uranus has 9 brighter rings as well as several fainter rings. Some of the larger rings are surrounded by belts of fine dust. The outermost ring is made up of ice boulders several feet across. The rings may have been formed by the break up of a small moon </li></ul>
  6. 6. Gravity <ul><li>Although Uranus is much larger than Earth, its surface gravity is less than the surface gravity on Earth. The surface gravity on Uranus is about 86% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 86 pounds on Uranus. </li></ul>
  7. 7. What made up of <ul><li>Uranus is made up of gases and is not solid like Earth. This makes Uranus very light for its size. Uranus' atmosphere is made up of hydrogen, helium and methane. </li></ul>
  8. 8. How old <ul><li>Uranus was formed at the same time as the rest of the solar system, from a large spinning disk of gas and dust. Astronomers think that all this happened about 4.6 billion years ago! So Uranus is about 4.6 billion years old. </li></ul>
  9. 9. Why is Uranus blue? <ul><li>The methane in Uranus' upper atmosphere absorbs the red light from the sun but reflects the blue light from the sun back into space. </li></ul>
  10. 10. How long does it take to get to Uranus from Earth? <ul><li>Voyager 2 took almost nine and a half years to reach Uranus. </li></ul>
  11. 11. How long does it take Uranus to go around the sun? <ul><li>Uranus revolves or orbits around the sun once every 84 Earth years, or once every 30,687 Earth days. Uranus travels at an average speed of 15,290 miles per hour or 24,607 kilometers per hour in its orbit around the sun. </li></ul>
