The surface gravity of Neptune is 36.6 feet per second squared, or 11.5 meters per second squared. A person weighing 100 pounds on the Earth would weigh about 114 pounds on Neptune.Know More
The mass of Neptune is more than 17 times greater than the Earth. By comparison, if the Earth were reduced to the size of a nickel, Neptune would be the size of a baseball.
Neptune is a gas giant composed of water, ammonia and methane surrounding an Earth-sized solid core. The atmosphere is mostly hydrogen, helium and methane.
Neptune is the eighth planet and is the farthest from the sun. It was the first planet whose existence was predicted from mathematical calculations before it was observed through a telescope.Learn More
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 >
The surface gravity of Pluto is measured according to its gravitational acceleration, calculated as approximately 0.58 meters per second squared. By contrast, the acceleration of Earth's surface gravity is measured at roughly 9.80 meters per second squared.Full Answer >
The force of gravity on Jupiter is 81.3 feet per second squared, or 2.528 grams. This means that a person who weighs 150 pounds on Earth would weigh 379.2 pounds on Jupiter.Full Answer >
Mars' gravitational pull is 3.724 meters per second on the surface. The pull is 62 percent weaker than Earth's surface gravity which exerts a pull of 9.8 meters per second.Full Answer >
