Definition

Mars is the fourth planet from the sun and the second-smallest planet in our solar system. It is a cold, dry, and dusty place with a thin atmosphere. Mars is also the only planet in our solar system besides Earth that has signs of liquid water on its surface.

Scientists think that Mars was once much more like Earth, with a thicker atmosphere and a warmer climate. However, something happened to Mars billions of years ago that caused its atmosphere to thin and its climate to cool.

Today, Mars is a cold, dry, and dusty place with a thin atmosphere. The average temperature on Mars is -87 degrees Fahrenheit. There is no liquid water on the surface of Mars, but scientists have found evidence that there may be liquid water underground.

Mars is a fascinating planet, and scientists are still learning about it. We may one day find evidence that Mars once had life, or even that it could support life today.
