Mars
Mercury has the smallest mass of the 8 planets at 5.5% of the mass of the Earth. It therefore has the least gravity of all the planets.
Mars has the lowest gravity of the planets in our solar system.Some people believe than you would weigh the least of Mercury because it is the smallest planet, but Mercury is more dense than Mars and thus has a stronger gravitation force.It's not much between them:Mars - 0.376gMercury 0.38 gEarth (For comparison) 0.99732 gSee related link for the other planets.Mars or Mercury. Both have a surface gravity of about 38% of Earth's.
Earth > Venus > Mercury > Mars
Not by the Martian gravity at any rate. The gravity on the surface of Mars is weaker than on Mercury.
Why does Mercury and Mars have less gravity than Earth because they both have less mass than does the Earth.
Mars has the lowest surface gravity (0.376g), just a little lower than that of Mercury (0.38g
This does seem odd. Mars, with a mass that is about twice the mass of Mercury, has about the same surface gravity. Mars' mass is about .107 the mass of earth, and the mass of Mercury is about .055 the mass of earth. The surface gravity on Mars is about .38 times the surface gravity of earth, and the surface gravity of Mercury is about .38 times the surface gravity of earth as well. The difference is that the mean density of Mercury is about 5.43 grams per cubic centimeter, and the mean density of Mars is about 3.93 grams per cubic centimeter. Mercury is quite a bit more dense, so if you stand on Mercury you are much closer to the center of gravity of the planet. Mercury has a tiny slightly bit more gravity than mercury though.
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
By a very slim margin you would weigh the least on Mercury, where gravity is 37% the strength of it is on Earth. This is only a tiny bit less than the gravity of Mars, which is 37.11% of Earth's gravity.
You would weigh the least on Mercury, due to its smaller size and weaker gravity compared to Earth.
Mercury is the least massive of all the planets. The least massive planet is Mercury (0.055 Earths). However, the planet with the weakest gravity is Mars. I am of course not treating Pluto as a Planet (as it is no longer categorized as a planet), if I were to count Pluto then it would be the least massive ( 0.0021 Earths).
Mars, although Mercury is a very close second.Mercury is the smallest of the 8 major planets, and has the least mass. However, it is dense, and its smaller size means that it has slightly higher gravity *at its surface* than Mars does, even though Mars has about twice the mass of Mercury.Mars = 0.376 g (Earth gravity)Mercury = 0.38 g (Earth gravity)* Previously, Pluto had the smallest size and lowest surface gravity. But it is now classified with other dwarf planets and distant planetary bodies, which so far are all smaller than Mercury.
