  1. URANUS By Nick Towers

  2. The Name • Uranus got its name from the god of the sky. • Uranus means “father of the titans” in Greek Mythology.

  3. Discovery • First planet discovered in modern times. • Discovered by William Herschel on March 13, 1781. • Uranus was spotted many other times, but it was looked at as a star.

  4. Planet Measurements Mass: 8.683e25 kg Volume: 68,330,000,000,000 km Density: 1.27 g/cm Gravity: 8.69 m/s 3 3 2

  5. Float or Sink in Water • Uranus would float in water because of its low density. • It is the second least dense planet in the solar system.

  6. Atmosphere • Icy atmosphere • 83% hydrogen • 15% helium • 2% methane • Thick atmosphere

  7. Distance • Uranus is the 7th planet from the sun. • 2,877,000,000 km from the Sun. • 2,057,000,000 km from Earth.

  8. Orbit and Rotation • Takes 84 earth years to orbit the sun. • Takes 17 hours and 14 minutes to rotate on its own axis.

  9. Temperature • -243 to -370 degrees F • The temperature on Uranus is much colder than on earth.

  10. Composition/Appearance • Uranus is a gas giant because its surface lacks a solid. • The internal composition contains hydrogen, helium, and methane. • Uranus is one of the outer planets. Uranus looks very similar to Neptune. Uranus is a blue/green color. It has rings orbiting it, but they are hard to see.

  11. Rings There are rings around Uranus , but they are very difficult to see. James Elliot, Edward Dunham, and Douglas Mink discovered it when Uranus passed in front of a star and was noticed that there were dips in the brightness. • 13 rings, Color: Blue-ish, clear. It is made of Black dust particles, large rocks, and helium.

  12. Water • Not sure, but astronomers suspect there could have been lots of water.

  13. Weather • It is beyond freezing cold. • It is the coldest planet in the Solar System.

  14. Moons • Uranus does have moons orbit around it. • There are 27 moons

  15. If a human went to Uranus they would probably freeze to death.

  16. Something Special • Uranus rotates from top to bottom unlike all of the other planets which rotate side to side. • Uranus is the coldest planet in the Solar System. • Uranus has rings. • It was the first planet discovered in modern times. • Uranus is the 7th planet from the sun.
