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 be visible in the dawn sky, rising at 01:47 (EDT) – 3 hours and 34 minutes before the Sun – and reaching an altitude of 31° above the eastern horizon before fading from view as dawn breaks around 04:39.
