Uranus

 

This distant, blue-green planet is something of a mystery.  Even after Voyager-2's flyby, there remains a great deal that is unknown about Uranus.

 
The correct pronunciation of this planet is  "Your-uh-nus" not "Your-anus."  Uranus is a giant planet, about 4 times the diameter of Earth. Through a telescope it looks like a tiny greenish or bluish disk. This is because it has methane in its atmosphere that absorbs other colors. It has 5 large moons named, Ariel, Umbriel, Titania, Miranda, and Oberon. All of the moons appear to be made up of rock and ice. Uranus also has a set of nine thin rings around it as observed by Voyager 2.
