What do you know about Mars? What does it look like?

Mars is the 【小题1】 planet from the sun in our solar system and 【小题2】 after Mars, the Roman god of war. Its diameter is 53% as 【小题3】 as that of the earth. Mars gets around the sun 【小题4】 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 【小题5】 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 【小题6】 weighs 90 kilos on earth weighs only 36 kilos on Mars. The 【小题7】 on Mars is between -138℃ and 28℃. The air 【小题8】 only 0.13% oxygen.

It takes a spaceship about eight months 【小题9】 Mars from the earth when the two 【小题10】 are closest to each other. Scientists are still searching for more information about Mars.
