Martian Year. For any planet, a year is the time it takes to make one orbit around the sun. Because Mars is farther away from the sun, it has to travel a greater distance around the sun. It takes Mars about twice as long as it does for Earth to make one circle around the sun. Therefore, a year on Mars lasts twice as long. Mars Seasons. Mars has four seasons, roughly twice as long as those on Earth, but with more variation given Mars' eccentric orbit and the fact its orbital speed varies more as result (fastest when at perihelion; slowest at aphelion).
