The following chart shows the distance of Mercury 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 Mercury from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Mercury to Earth
Between January 2013 and December 2100 the closest approach of Mercury to Earth happens on Sun May 31 2015 at a distance of 0.54903598 Astronomical Units, or 82,134,613 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 Mercury, 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.
Mercury rise and set times
The rise and set times are defined as the time at which the upper limb of Mercury 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.
