Uranus

Uranus is a big, icy blue planet that rolls around the Sun on its side. It looks very different from most other planets because it tilts like a fallen bowling ball.

Weather and air

Uranus has very cold air and strong winds, and its atmosphere is made mostly of hydrogen, helium, and methane which gives it a blue color. There is no breathable air for people.

A few interesting things

  • Uranus spins on its side with its axis almost lying in its orbit.
  • Its blue-green color comes from methane gas in the atmosphere.
  • Seasons on Uranus last about 20 Earth years because it takes 84 Earth years to orbit the Sun.
  • It has faint rings, but they are much darker and harder to see than Saturn’s.
  • Uranus is very cold—one of the coldest planets in our solar system.
  • A day on Uranus is about 17 hours long, even though a year is 84 Earth years.

Uranus has 27 moons. Here are three of the moons.
