Uranus
Uranus is currently in the constellation of Aries. The current Right Ascension of Uranus is 02h 17m 06s and the Declination is +13° 15’ 12” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current magnitude of Uranus is 5.77 (JPL).
Summary of key facts about Uranus [tip: you can also create a Quick Access page for this data if you access it frequently and would like to have a simpler view]:
- Uranus is above the horizon from Greenwich, United Kingdom [change].
- It is visible looking in the East-South-East direction at an altitude of 28° above the horizon.
- 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.

Uranus Distance from Earth
The distance of Uranus from Earth is currently 2,941,057,298 kilometers, equivalent to 19.659754 Astronomical Units. Light takes 2 hours, 43 minutes and 30.3112 seconds to travel from Uranus and arrive to us.
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 of Uranus to Earth
Between January 1900 and January 2100, the closest approach of Uranus to Earth happens on Wed Mar 15 2051 at a distance of 17.289890 Astronomical Units, or 2,586,530,766 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Uranus brightness
The current visual magnitude of Uranus is 5.77.
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.
Uranus rise and set times
Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London
Today's Uranus rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):
The rise and set times are defined as the time at which the upper limb of Uranus touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
