Uranus

Black and white picture of Uranus.

 

1,783,980,000 miles from the sun.

One of its years is equal 84 Earth Years.

Its day is 16.8 Earth hours and it spins completely sideways.

Its diameter is 32,193 miles across.

Its lower atmosphere is 50% water!  The rest is Methane

(hence the blue color), ammonia, and helium.

Its temperature is -344o degrees Fahrenheit.

Uranus could have used a V-8.  It spins completely on its side.  Where other planets have their North and South pole on their tops and bottoms, Uranus has its poles on its front and back.  And its poor moons, they spin over the top and around, instead of around the middle.  Then, to top it off, Uranus has a bunch of very visible rings (11 of them), much like Saturn (but not quite as many).   Uranus's upper atmosphere is 98% hydrogen and helium, the remaining is methane.   And, its gravity is similar to Venus's.  It truly is a work of art.

Uranus has 15 known moons, so we can imagine the sight of them spinning so strangely.  Uranus's gravity is about the same as Venus, but Uranus is much larger.  Titania is Uranus's largest moon, about 982 miles in diameter.   Ariel is a much smaller moon (pictured below), but strangely it does not have all the visible craters that most moons have.  This is because it also has volcanoes whose activity covers the craters.

 

Uranus's moon, Ariel, 1160 km across, has volcanoes.

Uranus's rings, not nearly many as Saturn, but hundreds.

Titania, Uranus's largest Moon at 1580 km, is half the size Earth's moon.

Uranus Moon, Miranda, is the smallest 480 km.
