Saturn is the sixth planet from the Sun and is the second largest planet in the Solar System after Jupiter. It has a diameter of 116,460 kilometers and a mass of 5.68 x 10^26 kilograms, making it approximately 95 times more massive than Earth. Saturn is a gas giant planet with a composition similar to Jupiter, primarily composed of hydrogen and helium with trace amounts of other gases. The planet is famous for its extensive ring system, consisting of numerous narrow, bright rings composed of ice particles, rock debris, and dust. Saturn has a day length of 10.7 hours and an orbital period of 29.4 Earth years. The planet has 82 known moons, with the largest being Titan, a moon with a thick atmosphere and the only known moon with stable liquid on its surface. The planet has been explored by multiple spacecraft, including NASA's Cassini-Huygens mission, which spent 13 years in orbit around Saturn and its moons.

Saturn is currently in the constellation of Aquarius.

The current Right Ascension of Saturn is 22h 35m 42s and the Declination is -10° 29’ 22” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current magnitude of Saturn is 0.86 (JPL).

Saturn Distance from Earth

The distance of Saturn from Earth is currently 1,452,454,160 kilometers, equivalent to 9.709056 Astronomical Units. Light takes 1 hours, 20 minutes and 44.8656 seconds to travel from Saturn and arrive to us.

1 hours, 20 minutes and 44.8656 seconds

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 1 January 1600 and 30 December 2499, the closest approach of Saturn to Earth happens on Wed Dec 11 1619 at a distance of 8.012797 Astronomical Units, or 1,198,697,442 kilometers:

NOTE: values for the closest approach are computed with a sampling interval of 1 day.

Saturn Brightness and Light Curve

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.
