Distinguishing Features

Mars is known as the Red Planet, an appearance it gets from the surface being rich in iron oxide, a dust that covers the planet.

Much like Earth, Mars has two polar caps .

The surface of Mars is covered in over 43,000 large impact craters and many more besides that remain undiscovered.

Where is it in our Solar System?

Mars is the fourth planet from the Sun, sitting between Earth and Jupiter, at an incredible 142,000,000 miles, or 1.5 AU from our central star.  That is one and a half times the distance between the Earth and the Sun.  You would need to walk around the Earth’s equator over 5,700 times to equal that distance.

Interesting Facts

So far, Mars has the largest mountain in the Solar System, it is roughly three times the size of Everest at a staggering 15.6 miles high! The mountain is called Olympus Mons.

Mars is prone to huge dust storms enveloping and sweeping across the surface.

Currently, Mars is the only planet that we know of, that is completely inhabited by just robots.  This is due to the missions that humans have led to the Red Planet in which they can get the machinery to Mars, but have not been able to get the robot explorers back to Earth, so they instead roam the surface of Mars collecting data and sending it back to us, until it malfunctions.
