What Is the Gravity on Mercury?
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.
