Mars orbital period is equal to 687 Earth days. its orbital period is 687 (Earth) days.
Orbit and Rotation of Mars. Mars distance from the Sun is 230 million km and its orbital period is equal to 687 Earth days. For this planet, the solar day is only a bit longer than that of the Earth’s day which is 24 hours, 39 minutes and 35.244 seconds. An entire Martian year would equal 1.8809 in Earth years.  The Mars cycle of eccentricity is 96,000 Earth years compared to the Earth's cycle of 100,000 years. However, Mars also has a much longer cycle of eccentricity with a period of 2.2 million Earth years, and this overshadows the 96,000 year cycle in the eccentricity graphs. For the last 35,000 years Mars' orbit has been getting slightly more eccentric because of the gravitational effects of the other planets. Earlier it was mentioned that Mars followed a highly eccentric orbit. The orbit of Mars is the second most eccentric in the Solar System. Only Mercury’s orbit is more eccentric. At perihelion Mars is 206,655,215 km from the Sun and at aphelion it is 249,232,432 km distant. That is a variation of of just under 42,600,000 km. The average distance from Mars to the Sun (called the semi-major axis) is 228 million km.  The orbital period is the time taken for a given object to make one complete orbit around another object. When mentioned without further qualification in astronomy this refers to the sidereal period of an astronomical object, which is calculated with respect to the stars.  The orbital period of the earth is 365.256366 days, or 1.0000175 years. About a year. That's how we define the year-it's the time it takes the earth to make one complete orb … ital trip around the sun. Since the earth and mars both orbit the sun, the distance is changing all the … time. In 2003, the orbits lined up, and Mars came within 55 million kilometers. Driving your car at 50km/hr, it would take 114 years to reach Mars when it was 55 million kilometers away. Mars' period of revolution in its orbit around the sun is 1.88 earth years (687 earth days).

Driving your car at 50km/hr, it would take 114 years to reach Mars when it was 55 million kilometers away. ORBIT AND ROTATION ON PLANET MARS. Mars' average distance from the Sun is roughly 230 million km (1.5 AU) and its orbital period is 687 (Earth) days. The solar day (or sol) on Mars is only slightly longer than an Earth day: 24 hours, 39 minutes, and 35.244 seconds. A Martian year is equal to 1.8809 Earth years, or 1 year, 320 days, and 18.2 hours. However, Mars also has a much longer cycle of eccentricity with a period of 2.2 million Earth years, and this overshadows the 96,000 year cycle in the eccentricity graphs. For the last 35,000 years Mars' orbit has been getting slightly more eccentric because of the gravitational effects of the other planets. Mars's cycle of eccentricity is 96,000 Earth years compared to Earth's cycle of 100,000 years. Mars also has a much longer cycle of eccentricity with a period of 2.2 million Earth years, and this overshadows the 96,000-year cycle in the eccentricity graphs. For the last 35,000 years, the orbit of Mars has been getting slightly more eccentric because of the gravitational effects of the other planets. Mars is the fourth planet from the Sun and the second smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the Red Planet because the iron oxide prevalent on its surface gives it a reddish appearance. Mars's average distance from the Sun is roughly 230 million kilometres (143,000,000 mi), and its orbital period is 687 (Earth) days. The solar day (or sol) on Mars is only slightly longer than an Earth day: 24 hours, 39 minutes, and 35.244 seconds.

The average distance from Mars to the Sun (called the semi-major axis) is 228 million km. It takes Mars approximately 687 Earth days to complete on orbit. The orbit of a planet varies in relation to the gravitational influences of the bodies around it, so the eccentricity can change over time.
