Our year is On Mars it takes Since the Moon's orbit centers on the Earth, rather than the Sun, it would be a little confusing to think of the Moon's orbit as a "year". Instead, this cycle of the Moon orbiting the Earth is much closer to our calendar system of "months".
It takes If that number looks familiar, it's because the orbital period of the Moon is exactly the same as its rotational period. This is the reason we can never see the far side of the Moon from Earth--it's always facing away from us. When Nature Strikes - Earthquakes.

What is the periodof the Earth? The Moon? One of the definitions Webster's dictionary gives for "period" is "the completion of a cycle". When we're thinking about the motions of planets, a period can be defined in a couple of different ways.
The "rotational period" of an object in the solar system is the amount of time it takes for the object to complete one turn, or rotate on its axis. We call the rotational period of Earth a "day". That takes us into night and finally to a new day with the Sun rising once again. However the length of a day can be defined in two ways — a sidereal day and a solar day. The time it takes for a planet to spin once so that the stars appear in the same position again in the night sky is known as a sidereal day.
On the Earth that is 23 hours 56 minutes and 4 seconds. This is the amount of time it takes for a planet to spin on its axis so that the Sun appears in the same position in the daytime sky typically when the Sun is on the local meridian. For the Earth a solar day is 24 hours long on average. That means it takes slightly longer each day — about four minutes — for the Sun to appear in the same part of the sky as it did the previous day. There are some planets with very short days like Jupiter.
The length of a Jovian sidereal day is 9 hours, 55 minutes and 30 seconds. Other planets have much longer days — Venus has a sidereal day of days and 36 minutes.
However Venus has retrograde motion so it spins in a clockwise direction, meaning its solar day days and 18 hours ends up being shorter than its sidereal day. Mars is a planet with a very similar daily cycle to the Earth. Its sidereal day is 24 hours, 37 minutes and 22 seconds, and its solar day 24 hours, 39 minutes and 35 seconds. But how would we have to adapt if we were seriously considering going to live on Mars? The length of an Earth year is on average This is highlighted by the Earth-Sun distance being shorter in the winter season in the northern hemisphere and longer during the summer.
Temperatures are generally higher in the summer, even though we're actually further from the Sun. Since Mars is further from the Sun compared to the Earth, a Martian year is longer: days. Its 25 degree axial tilt means that Mars also experiences seasons. The average temperature on Mars is degrees Centigrade. Mars is the fourth planet from the Sun and orbits the Sun at an average distance of approximately million miles million km.
Mars rotates on its axis, completing one revolution every The axis of Mars is tilted at 25 degrees and 12 minutes relative to its orbital plane about the Sun. This produces seasons on the surface of Mars, similar to the seasons on Earth. Mars completes one orbital revolution around the Sun every 1. Two small natural satellites, Demos and Phobos, orbit Mars. Mars has no magnetic field to protect the surface from radiation from the Sun.
Many of the features on the surface of Mars resemble features on the Earth; there are great dusty plains, there are large volcanoes, and there is a large rift valley along the equator. Similar to the Earth, Mars has ice caps at the poles which grow and shrink with the seasons.
