Q:

What is the gravity on Mercury?

A:

Quick Answer

The surface gravity on Mercury is 3.7 meters per second squared, which is 38 percent of the surface gravity on Earth. Surface gravity is typically measured in acceleration units.

Full Answer

A person weighs 38 percent of his Earth weight on Mercury. If a man weighs 180 pounds on Earth, he would weigh 68.4 pounds on Mercury. Because strength is not affected by gravity, that same man would be able to jump 2.6 times higher than he can on Earth. Comparisons notwithstanding, no one is able to live on Mercury, the closest planet to the sun. Temperatures on this planet range from approximately minus 300 degrees Fahrenheit all the way up to 800 degrees Fahrenheit.

  • Q:

    How strong is the gravitational pull of the planet Mars?

    A:

    The gravitational pull on Mars is 38 percent that of the gravity of Earth, explains researchers at the California Institute of Technology. The lower gravitational force is due to the smaller mass of the planet.

  • Q:

    What is the gravitational force of Mars?

    A:

    The gravitational force of Mars is 38 percent of Earth's gravity. This low gravity is due to the fact that Mars only possesses 11 percent of the Earth's mass and 15 percent of the Earth's volume. The planet's significantly lower mass and size reduces the gravity it exerts on objects.

  • Q:

    How much gravity does Mars have?

    A:

    The force of gravity experienced on the surface of Mars is only 38 percent as strong as the Earth's surface gravity. The weaker gravitational force of Mars is due to its smaller mass and lower density.

    How long does it take for Mercury to rotate on its axis?

    A:

    It takes a total 1407.5 hours, or 58.646 Earth days, for Mercury to make a complete rotation on its axis. A day on Earth is only 23.934 hours long, which pales in comparison to Mercury's extremely long days. Mercury makes a full rotation around the sun in 88 Earth days, and it is the closest planet to the sun, which is a distance of 36 million miles.
