Mars is currently in the constellation of Taurus. The current Right Ascension of Mars is 03h 42m 04s and the Declination is +18° 05’ 36” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current magnitude of Mars is 0.01 (JPL).
Summary of key facts about Mars [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]:
- Mars is above the horizon from Greenwich, United Kingdom [change].
- It is visible looking in the West-North-West direction at an altitude of 8° above the horizon.
- Given its current magnitude, Mars is visible to the naked eye, even from highly light polluted areas.
- See also Mars rise and set times.

Mars Distance from Earth
The following chart shows the distance of Mars 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 Mars from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Mars to Earth
Between January 2013 and December 2100, the closest approach of Mars to Earth happens on Mon Aug 31 2082 at a distance of 0.373566 Astronomical Units, or 55,884,640 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 Mars, 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.
Mars rise and set times
The rise and set times are defined as the time at which the upper limb of Mars 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.
