Mars/Earth Comparison Table Mars is only about one-half the diameter of Earth, but both planets have roughly the same amount of dry land surface area. This is because over two-thirds of the Earth's surface is covered by oceans, whereas the present surface of Mars has no liquid water.
1. Earth-Mars Comparison . This image compares Mars and Earth in their correct relative sizes. Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers). Note the difference in color between the two planets. Almost 70% of Earth's surface is covered by liquid water.

In the entire solar system, Mars boasts general features that are some of the biggest, widest, and deepest.
Mars is roughly half the size of the Earth. It has a diameter of 4,222 miles, compared to Earth's 7,962 miles at the equator. Mars is 53% as large as Earth; this means that Mars has a gravity that is less than 40% of what people feel on Earth.
Mars is nearly twice as large as the Moon and a little over half the size of Earth, according to the Center for Mars Exploration. The diameter of Mars is about 6,786 kilometers (4,217 miles), compared to that of Earth, which is about 12,756 kilometers (7,926 miles). In addition, Earth has a mass that is 10 times greater.
