Saturn
Saturn is currently in the constellation of Sagittarius. The current Right Ascension of Saturn is 19h 54m 35s and the Declination is -21° 05’ 58” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current magnitude of Saturn is 1.02 (JPL).
Summary of key facts about Saturn [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]:
- Saturn is below the horizon from Greenwich, United Kingdom [change].
- Given its current magnitude, Saturn is visible to the naked eye, easy and bright under dark skyes, might be more difficult from heavily light pollyuted areas.
- See also Saturn rise and set times.

Saturn Distance from Earth
The distance of Saturn from Earth is currently 1,359,585,222 kilometers, equivalent to 9.088266 Astronomical Units. Light takes 1 hours, 15 minutes and 35.0881 seconds to travel from Saturn and arrive to us.
The following chart shows the distance of Saturn 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 Saturn from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Saturn to Earth
Between January 1900 and January 2100 the closest approach of Saturn to Earth happens on Mon Dec 21 1914 at a distance of 8.03044007 Astronomical Units, or 1,201,336,738 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Saturn brightness
The current visual magnitude of Saturn is 1.02.
The following chart is the predicted light curve (visual magnitude as a function of time) of Saturn, 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.
Saturn rise and set times
Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London
Today's Saturn 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 Saturn 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.
