Mars
is the 4th planet from the Sun. It is called the red planet. It is about 142 million
miles from the Sun. Mars is made of rock that has lots of iron in it. The iron in the rock
and soil make the planet look red.Astronauts haven't walked on Mars, but space
probes have landed there. Viking I was the first probe and it landed in 1976. They were
looking for signs of life. Some scientists think they found a kind of life form called
microbes in the rock samples. Mars has the biggest volcano in the solar system. It's much
higher than the tallest volcano on earth. Mars looks like a red star in the night
sky. by Kristan and Abbi |
