Uranus

─ Uranus atmosphere mostly made up of hydrogen (H2) and helium (He), with a small amount of methane (CH4). The methane gives it a blue-green tint.

─ It also has faint rings. The inner rings are narrow and dark. The outer rings are brightly colored and easier to see.

─ Unlike any other planet, it rotates on its side, and also rotates in the opposite direction as most other planets.

─ If you weigh 45 kg (100 pounds) on Earth, you would weigh 41 kg (91 pounds) on Uranus.
