Full Answer

Uranus is the seventh planet from the sun and takes about 84 Earth years to complete an orbit. It is considered one of the four gas giants, along with Jupiter, Saturn and Neptune, because it is composed entirely of gas. William Herschel used a telescope to identify Uranus as a planet in 1781. The planet is unusual in that its axis is tilted at 98 degrees, causing it to rotate on its side. Uranus has 27 moons and at least 13 known rings.
