"Mars takes 686.971 Earth days to orbit the Sun. That means that one Martian year is equal to 1.88 Earth years."
"If you were standing on Mars, a year would take 668.5921 sols. In other words, Mars rotates 668.5921 during one orbit about the Sun."
Also, it is interesting to know the length of a day on Mars:
"A sidereal day on Mars is the length of time that it takes the planet to rotate once on its axis. A sidereal day on Mars lasts 24 hours 37 minutes and 22 seconds. The solar day is how long it takes the Sun to return to the meridian. This position changes slightly each day, but a solar day on Mars lasts 24 hours 39 minutes and 35 seconds."

It takes Mars 687 days for it to revolve once around the sun.
Venus takes 225 days to complete one revoluton
Mars revolves around the Sun in about 687 Earth days, or 669 Mars days.
A lunar cycle is the time it takes for the moon to make a full revolution around the Earth. It takes about 29.5 days.
the sun does not rotate around itself, but the earth takes 365.25 days to make one revolution around the sun.
Mars period of revolution around the sun, its orbit, is 686.971 Earth days long. The time it takes to make one spin on its axis relative to the background stars is 24h:37min:22.663sec. The apparent day or solar day on mars is 24h : 39min : 35sec.
Mars takes around 687 days to make one orbit of our sun.
It travels about 1,432,183,600 km to complete one revolution.

Mars rotation is 24 hours 39 minutes and 35 seconds. Mars only rotates 39 minutes slower than earth. 1.88 years for revolution Mars period of revolution around the sun, its orbit, is 686.97 Earth days long. The time it takes to make one spin on its axis relative to the background stars is 24h:37min:22.7sec
It takes nearly twice as much time for Mars to get around the Sun than Earth. In Earth days, it takes Mars 686.980 days to make the same orbit.
On Earth, it takes us 365 1/4 days to make one revolution on Earth. It takes 88 days for Mercury to revolve around the sun. It takes 225 days on Venus to make a full revolution around the sun. It takes Mars 1.9 years to make one revolution around the sun. Jupiter takes 11.9 years to make one revoultion around the sun. Saturn takes 29.5 years to make one revolution around the sun. It takes Uranus 84 years to make one full trip around the sun. It takes Neptune 165 years to do the same thing. I am includeing Pluto too for those Pluto haters out there. It take Pluto 249 years to make one complete revolution around the sun.
