Uranus - Information on Uranus

Scientists classify Uranus as a Jovian planet or gas giant. It has a rocky core, surrounded by a huge ocean of water mixed with rocky material. Its atmosphere is about 83% hydrogen, 15% helium and 2% methane. While most other plantes rotate on an axis which is nearly perpendicular to their orbit, Uranus's axis is closer to parallel. There is some debate as to which pole is north.
