Mars completes one revolution on its axis in 24.6 hours. It takes 1.88 Earth years for Mars to make one revolution around the sun. Mars is over 140 million miles from the sun.Continue Reading
The tilt of Mars' axis is at 25 degrees, which is close to Earth's tilt and rotation time. Its elliptical orbit makes for a longer revolution around the sun than Earth's circular orbit, and it makes the seasons extreme. Deimos, Mars' farthest moon, makes one revolution around the planet in just under 30 hours. The closest moon, Phobos, makes three revolutions in a day, which is about one revolution every eight hours.
The total circumference of Mars' orbit is about 888 million miles, compared with approximately 584 million miles for the orbital circumference of Earth. Mars' revolutionary orbit is also about 5.6 times more elliptical than Earth's, accounting for the large difference in orbital circumference. Mars follows its revolutionary path at an average speed of 53,858 miles per hour and comes within 128,409,598 miles of the Sun at its closest approach.Learn more about Planets
