Mars is the fourth planet from the sun. It is 141 million miles away from the sun. A year on Mars is 687 Earth-days long. One day is about the same as on Earth： 24. 25 hours long.

Mars is about half the size of Earth. Because Mars is smaller than Earth，its gravity is also less. If you weighed 100 pounds on Earth, you'd weigh about 38 pounds on Mars.

Mars' surface looks like a red desert. There are mountains, canyons(峡谷).and volcanoes (火山)and so on. It is a dry planet without any liquid water(液态水).It does have ice caps at its north and south. Some of this ice is frozen(冻结的)carbon dioxide.

Evidence shows that Mars once had rivers, streams, lakes, and maybe even an ocean. Scientists guess that there once was water on the surface of Mars that created these. Today the only water on Mars is either frozen in the ice caps or underground.

Mars has mountains that are much higher than the mountains on Earth. Olympus Mons, the biggest volcano in the whole solar system， stands 17 miles tall！Mars also has bigger, deeper canyons than Earth's. Some of these are sixty miles long and five or six miles deep. How amazing！
