At just 0.376 of the Earth standard (or 0.376 g), a person who weighs 100 kg on Earth would weigh only 38 kg on Mars. This difference in surface gravity is due to a number of factors – mass,...
The gravity of Mars is a natural phenomenon, due to the law of gravity, or gravitation, by which all things with mass around the planet Mars are brought towards it. It is weaker than Earth's gravity due to the planet's smaller mass.
Scientists have calculated Mars' gravity based on Newton's Theory of Universal Gravitation, which states that the gravitational force exerted by an object is proportional to its mass. When...
Mars has two small moons, Phobos and Deimos, that may be captured asteroids. They're potato-shaped because they have too little mass for gravity to make them spherical. The moons get their names from the horses that pulled the chariot of the Greek god of war, Ares.
The gravity on Mars is 3.711 m/s², which is just 38 percent the gravity on Earth. Earth’s gravity is 9.807 m/s², compared to the moon’s gravity of 1.62 m/s² or just 17 percent of Earth’s gravity.
The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mars.

Mars is also similar to Earth in many key respects. However, when it comes to size, mass and density, Mars is comparatively small. In fact, its mean radius of 3.389 km is the equivalent of roughly...
Mars is less than 56 million km (35 million miles) from Earth at its closest approach, but it recedes to almost 400 million km (250 million miles) when the two planets are on opposite sides of the solar system. What is the size of Mars?
What is the gravity on Mars? The gravity on Mars is 62% lower than on the Earth. This means that a person who weighs 80 kg (176 lbs) on our planet would weigh only 30 kg (66 lbs) on Mars.
