Mars's 687-day orbit around the Sun will carry it to its closest point to the Sun – its perihelion – at a distance of 1.38 AU.

Unlike most of the planets, which follow almost exactly circular orbits around the Sun which only vary in their distance from the Sun by a few percent, Mars has a significantly elliptical orbit. Its distance from the Sun varies between 1.38 AU and 1.67 AU – a variation of over 20% – meaning that it receives 31% less heat and light from the Sun at aphelion as compared to perihelion.

Finding Mars

Mars's distance from the Sun doesn't affect its appearance. From South El Monte, at the moment of perihelion it will be visible between 20:34 and 05:54. It will become accessible at around 20:34, when it rises to an altitude of 7° above your eastern horizon. It will reach its highest point in the sky at 01:14, 41° above your southern horizon. It will become inaccessible at around 05:54 when it sinks below 7° above your south-western horizon.

The circumstances of this event were computed using the DE430 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.
