How big is Mars compared to the Earth?

Size and Distance With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. If Earth were the size of a nickel, Mars would be about as big as a raspberry.

Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers). In contrast, Mars now has no liquid water on its surface and is covered with bare rock and dust.

Is Mars or Earth older?

“Mars is believed to be geologically older than Earth, yet [both] formed out of the same material very close to each other,” Matthew Clement, the paper’s lead author and a graduate researcher in planetary science at the University of Oklahoma, told me.

Why is Mars the most similar to Earth?

Comparison to Earth: Of all the planets in the solar system, Mars is the most Earth-like in terms of its water patterns. Mars has polar ice caps that grow and recede with the seasons and has evidence of water channels similar to those on Earth today.
