Uranus

Like Jupiter and Saturn, Uranus is a Gas Giant and does not have a solid surface.

However, it is blue not yellow/orange because it has different chemicals at the top of the clouds because it is colder.

Uranus has rings, like Saturn, but they are much thinner and difficult to see.

Uranus was the first planet to be discovered in modern times (by William Herschel in 1781).

The only space-probe to go to Uranus was Voyager 2 in 1986.

Uranus has 27 known moons (as of May 2005). 22 are very small and most are close to Uranus. The other five (Miranda, Ariel, Umbriel, Titania and Oberon) are larger and further out.
