Mars is the fourth planet from the sun in our solar system and
is named after Mars, the Roman god of war. Its diameter is 53% as wide as that of the earth. Mars goes around the sun at a distance of about 228 million kilometers. You can tell which planet is Mars because it is bright red in the night sky. It looks like a red and orange ball. It's very beautiful. But during spring and summer, the surface of Mars is covered by strong storms. The gravity on the surface of Mars is about two-fifths as strong as it is on earth. So a person who weighs 90 kilos on earth weighs only 36 kilos on Mars. The temperature on Mars is between -138℃ and 28℃. The air has only 0.13% oxygen.
It takes a spaceship about eight months to reach Mars from the earth when the two planets are closest to each other. Scientists are still searching for more information about Mars. 1.Does Mars have a good climate for plants? Why?
