Uranus is the seventh planet from sunlight. It has planetary mass that is fourth-largest and the planetary radius in the Solar System. Uranus is similar in composition and both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. For this reason, scientists frequently classify Uranus and Neptune as"ice giants" to distinguish them from the gas giants. Uranus' atmosphere is very similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, but it contains more"ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. It has the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 K (−224 °C; −371 °F), and has a complex, layered cloud structure with water thought to make up the lowest clouds and methane that the uppermost layer of clouds.

The interior of Uranus is mainly composed of ices and rock.Like another giant planets, Uranus has a ring system, a magnetosphere, and numerous moons. The Uranian system has a configuration since its axis of rotation is tilted almost to the plane of its solar orbit. Where other planets have their equators its north west and south poles lie. In 1986, Uranus was shown by pictures from Voyager 2 without storms or the cloud bands related to the giant planets, as an almost featureless world in visible light. Voyager 2 remains the only spacecraft to see the planet. Observations from Earth have shown seasonal change and weather activity that was enhanced as Uranus approached its equinox. Wind speeds can reach 250 metres per second (900 km/h; 560 mph).
