The rotation of Mars is very similar to that of the Earth, with a rotation time of 24 hours, 37 minutes and 22.6 seconds. A day and night on Mars is slightly longer than a day and night on Earth. Mars makes a revolution of about 687 days, and a year of Mars is about two years for the Earth.

Mars is one of the nine planets, ranking fourth in the sun from near to far. To the naked eye, Mars is a striking lux star, moving slowly among stars.

The soil on the surface of Mars contains a lot of iron oxide. Due to long-term exposure to ultraviolet rays, iron will form a layer of red and yellow oxides. To exaggerate, Mars is like a world full of rust. Because Mars is far away from the sun, the solar radiation energy it receives is only 43% of that of the earth, so the average temperature on the ground is about 30 degrees Celsius lower than that of the earth, and the temperature difference between day and night can reach hundreds of degrees Celsius. Near the equator of Mars, the highest temperature can reach about 20℃. Mars also has an atmosphere. Its main component is carbon dioxide, accounting for about 95%, and a very small amount of carbon monoxide and water vapor.
