Uranus is the seventh planet from the sun at a distance of about 2.9 billion km (1.8 billion miles) or 19.19 AU.
Uranus is an ice giant, with faint rings. The inner rings are narrow and dark and the outer rings are brightly coloured..
Uranus has an atmosphere which is mostly made up of hydrogen and helium with a small amount of methane which causes the planet to have a blue tint. Most of the planet’s mass is made up of a hot dense fluid of “icy” materials – water, methane and ammonia above a small rocky core.
Uranus is the only giant planet whose equator is nearly at right angles to its orbit. It is nearly the same size as the other ‘ice giant’, Neptune.
Uranus has 27 moons, many named after characters from the works of William Shakespeare and Alexander Pope such as Miranda, Titania, Oberon and Umbriel.
One day on Uranus takes about 17 hours (the time it takes for Uranus to rotate or spin once.) A complete orbit around the sun takes about 84 Earth years.
Uranus is not visible to the naked eye but it became the first planet discovered with the use of a telescope. It was discovered by William Herschel.
Voyager 2 is the only spacecraft to have visited Uranus.
