Jupiter is currently in the constellation of Capricornus. The current Right Ascension of Jupiter is 20h 39m 25s and the Declination is -18° 56’ 13” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current magnitude of Jupiter is -1.95 (JPL).
Summary of key facts about Jupiter [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]:
- Jupiter is above the horizon from Greenwich, United Kingdom [change].
- It is visible looking in the South-West direction at an altitude of 9° above the horizon.
- Given its current magnitude, Jupiter is visible to the naked eye, easyly even from highly light polluted areas.
- See also Jupiter rise and set times.

Jupiter Distance from Earth
The following chart shows the distance of Jupiter 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 Jupiter from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Jupiter to Earth
Between January 1900 and January 2100, the closest approach of Jupiter to Earth happens on Tue Oct 2 1951 at a distance of 3.948724 Astronomical Units, or 590,720,632 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
The following chart is the predicted light curve (visual magnitude as a function of time) of Jupiter, 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.
Jupiter rise and set times
The rise and set times are defined as the time at which the upper limb of Jupiter 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.
