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 Fairfield, at the moment of perihelion it will not be observable – it will reach its highest point in the sky during daytime and will be 2° below the horizon at dawn.
A chart of the path of Mars across the sky in 2026 can be found here, and a chart of its rising and setting times here.
The position of Mars at the moment it passes perihelion will be:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| Mars | 23h18m30s | 5°36'S | Aquarius | 1.2 | 4.1" |
The coordinates above are given in J2000.0.

Warning
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 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.
