  • 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.

Saturn Distance from Earth

The distance of Saturn from Earth is currently 1,504,772,362 kilometers, equivalent to 10.058782 Astronomical Units. Light takes 1 hours, 23 minutes and 39.3803 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.

Distance of Saturn from Earth between January 1900 and January 2100

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 8.030440 Astronomical Units, or 1,201,336,738 kilometers:

Saturn brightness

The current visual magnitude of Saturn is 1.38.

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):

Azimuth: 111.3°
Max altitude: 17.2°
Azimuth: 248.7°

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.
