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 0.37356580 Astronomical Units, or 55,884,648 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, consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
