Uranus is the seventh planet from the sun, and it is the third-largest planet in the solar system. It has a diameter of 50,724 kilometers and a mass of 8.68 x 10^25 kilograms, making it about 14.5 times more massive than Earth. Uranus is an ice giant planet, primarily composed of water, methane, and ammonia, and has the coldest atmosphere in the solar system with temperatures that can dip down to -224°C (-371°F). The planet has a tilted axis of rotation, which causes it to rotate on its side with its poles pointing towards the sun. Uranus has a day length of approximately 17.2 Earth hours and an orbital period of 84 Earth years. The planet has 27 known moons, with the largest being Titania and Oberon. Uranus also has a faint ring system, which was discovered in 1977 during a stellar occultation. Uranus has been explored by only one spacecraft, NASA's Voyager 2, which flew by the planet in 1986, providing the most detailed images and data of the planet and its moons to date.

Additional Information
Rise and Set Times
Today's rise, transit and set times of Uranus from Greenwich, UK (all times relative to the local timezone Europe/London):
- Uranus is below the horizon from Greenwich, UK.
- Given its current magnitude, Uranus is barely visible to naked eye under a clear and dark sky, easily visible with the help of a small binocular.

Distance from Earth
The distance of Uranus from Earth is currently
The following chart shows the distance of Uranus from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of Uranus from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach
Between 1 January 1600 and 30 December 2499, the closest approach of Uranus to Earth happens on Sat Mar 21 2471 at a distance of 17.260466 Astronomical Units, or 2,582,128,904 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Uranus, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
