  1. Mars has a dense core at its center between 930 and 1,300 miles (1,500 to 2,100 kilometers) in radius. It's made of iron, nickel, and sulfur. Surrounding the core is a rocky mantle between 770 and 1,170 miles (1,240 to 1,880 kilometers) thick, and above that, a crust made of iron, magnesium, aluminum, calcium, and potassium.

  2. Dec 16, 2016 · It also has a mean radius of 3,389.5 km, which works out to 0.532 Earth radii. The surface gravity of Mars can therefore be expressed mathematically as: 0.107/0.532², from which we get the value ...

  3. The larger the object's mass, the more difficult it is to move (i.e. Newton's second law, F=ma). The larger the object's mass, the stronger the planet's gravitational pull on it (i.e. Newton's law of universal gravitation, F=Gm1m2/r 2). So when the object has more mass, gravity pulls on it stronger, but it's harder to move, so they cancel out.

  5. As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours). Martian days are called sols – short for "solar day." A year on Mars lasts 669.6 sols, which is the same as 687 Earth days. Mars' axis of rotation is tilted 25 degrees with respect to the plane of its orbit around the Sun.

  6. The average gravitational acceleration on Mars is 3.72076 m/s², which is 62% lower than the 9.8 m/s² gravity of Earth. It means a thing of 100 pounds mass on Earth would have only 38 pounds mass on Mars. If a person jumps on the Mars surface, it would be 2.6 times higher than on Earth. Mars is a smaller planet and has a much lower volume ...

  8. 4 days ago · Mars, fourth planet in the solar system in order of distance from the Sun and seventh in size and mass. It is a periodically conspicuous reddish object in the night sky. Mars is designated by the symbol ♂. Sometimes called the Red Planet, Mars has long been associated with warfare and slaughter. It is named for the Roman god of war.
