The Fourth Planet in Our Solar System: Mars

The Romans named the planet Mars after the god of war. A reddish-orange planet with rusty colored rocks and dust, Mars is the fourth planet from the sun.

The surface of Mars has giant canyons and many large volcanoes. Only half the size of Earth, Mars is also orbited by two small moons—Phobos and Deimos. Mars is also different from Earth because the day on Mars is 30 minutes longer than Earth’s.

Scientists believe that water lies far under the surface of Mars. However, the atmosphere on this planet is too thin and the weather too cold for humans to survive on it.

Much has been discovered about Mars, but scientists indicate that there is still much to know about this planet.
