4. By the numbers
Third largest planet eccentricity 98 degree tilt Distance from the sun: AU Retrograde motion Rotates every 17 Earth hours Orbits the sun every 84 Earth years 27 moons Oberon and Titania are the largest Uranian moons, and were first to be discovered -- by William Herschel in rings

5. atmosphere
Composed of Hydrogen, Helium, Methane Uranus gets its blue-green color from methane gas in the atmosphere Seasons on Uranus last more than 20 years because the planet is tilted on its side. Scientists think it may have collided with a planet-sized object a long time ago. 80 percent or more of the mass of Uranus is consists mostly of icy materials (water, methane, and ammonia). Uranus is very cold, windy and, like most of the other planets, poisonous to humans. It is a gas planet like Jupiter, Saturn and Neptune.
