Q:

# What is the gravity on Mercury?

A:

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.

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.

NASA has observed that one day on Mercury is the equivalent of 59 days on Earth. A year on the planet, however, is only the length of 88 Earth days, since, at a distance of about 36 million miles, Mercury is the closest planet to the Sun.

Like Earth, Mercury is one of four terrestrial planets. It is known as a terrestrial planet because it has a solid ground surface made up of rock and metal. This surface makes Mercury's density very similar to that of the Earth and denser than gas planets, according to Universe Today.

The force of gravity on Uranus is 8.69 meters per second squared, which is also the speed at which dropped objects accelerate toward the surface of the planet. On Earth, objects accelerate at 9.78 meters per second squared. Uranus' gravity is approximately 89 percent of the force of Earth's gravity.
