One year on Mars about 687 Earth days. That's about 1.88 Earth years. The length of a sidereal year on Mars is about 686.98 Earth solar days (24 hours). More info aboutâ¦ Time Keeping on Mars: http://en.wikipedia.org/wiki/Timekeeping_on_Mars.
As on Earth, there is a second form of precession: the point of perihelion in Mars's orbit changes slowly, causing the anomalistic year to differ from the sidereal year. However, on Mars, this cycle is 43,000 years rather than 112,000 years as on Earth. On both Earth and Mars, these two precessions are in opposite directions, and therefore add, to make the precession cycle between the tropical and anomalistic years 21,000 years on Earth and 27,000 years on Mars.
