Uranus is one of the smaller gas planets in our solar system, but it is still large enough to hold sixty-four planets the size of Earth. Uranus, like Venus, rotates in an opposite direction of the other planets in the solar system, and its poles are sometimes pointed toward the sun. Cold methane gas gives Uranus a blue-green color. Uranus has strong winds, though not as strong as Saturn's. Wind speeds on Uranus can be as fast as 373 miles per hour. Compare that to the strongest winds on Earth; Hurricane Katrina was a category five hurricane, with wind speeds of over 156 miles per hour. Uranus has at least eleven rings made of particles the size of boulders. Uranus has at least twenty-one moons, though some are less than sixty-two feet wide.

Things to remember about Uranus:

  1. Uranus is the seventh planet from the sun.
  2. Uranus is a gas planet.
  3. Uranus rotates on its side.
  4. Uranus has strong winds.
  5. Uranus has at least twenty-one moons.
