One martian year is roughly 687 earth days long.
Take the length of the planet's orbit, divide it by the speed at which the planet is orbiting and VOILA! The "year."
The mariner spacecraft first landed on Mars 1971 I think.
1 year on mars is equal to 687 earth days even though the days on mars are about about the same time period hope this helps :)
Mars.
No. Every planet has different length years. The farther a planet is from the sun, the longer year it has. Mercury's year is only 88 of our days. Earth's year is exactly 1 year long. Jupiter's year is about 12 of our years, and Pluto's year is 248 of them.
