URANUS
HUGE
Uranus is about four times wider than Earth. If Earth were a large apple, Uranus would be the size of a basketball. SEVENTH WANDERER Uranus orbits our Sun, a star, and is the seventh planet from the Sun at a distance of about 1.8 billion miles. SHORT-ISH DAY, LONGISH YEAR Uranus takes about 17 hours to rotate once, and about 84 Earth years to complete an orbit of the Sun. ICE GIANT Uranus is an ice giant. Most of its mass is a hot, dense fluid of "icy" materials – water, methane and ammonia – above a small rocky core. URANUS IS BIG AND GASSY! Uranus has an atmosphere made mostly of molecular hydrogen and atomic helium, with a small amount of methane (yep, smelly too!). MANY MOONS Uranus has 27 known moons, and they are named after characters from the works of William Shakespeare and Alexander Pope. THE OTHER RINGED WORLD Uranus has 13 known rings. The inner rings are narrow and dark and the outer rings are brightly colored. |
A BIT LONELY
Voyager 2 is the only spacecraft to fly by Uranus. No spacecraft has orbited this distant planet to study it at length and up close.
LIFELESS
Uranus cannot support life as we know it.
ONE COOL FACT
Like Venus, Uranus rotates east to west. But Uranus is unique in that it rotates on its side.
