Sagan Planet Walk

An ice giant, tipped on its side
· Uranus has a rocky core, a mantle of water ice, ammonia ice, and methane ice, and a gaseous outer envelope of hydrogen, helium and a bit of methane gas, giving it a blue tint.
· Winds on Uranus can reach speeds of 900 km/hr, four times faster than the strongest winds on Earth!
· The poles of Uranus are tipped by 98°, so the planet rotates on its side as it orbits the Sun.
· Uranus has 13 distinct rings, which may have formed from the destruction of ancient moons.
· Because Uranus is tipped on its side, its polar regions are in almost complete darkness for nearly 21 years at a time!

...and its rocky-ice moons
· The moons of Uranus are composed of rock and ice. Their surfaces are heavily cratered.
· Miranda is home to Verona Rupes, the tallest cliff in our Solar System. At 20 km deep, it is ten times deeper than Earth's Grand Canyon!
· Voyager 2 detected silicate rock and water ice with hints of carbon dioxide on Ariel.
· Cupid, the smallest Uranian moon, is only 18 km in diameter.
