Mars orbit around the Sun will carry it to its furthest point from the Earth – its apogee – moving to a distance of 2.68 AU from us. Since the size and brightness of Mars in the night sky both decrease when it is far away from us, this marks the moment when it will appear smallest, measuring a mere 3.5 arcsec in diameter. However, in practice, it will be rather too close to the Sun for observation, at an angular separation of only 1.8848362869095747° from it, as it will be close to solar conjunction.
The exact position of Mars at the moment it passes apogee will be:

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
