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
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.
Well, honey, gravity ain't picky - it's the same everywhere! Both Mars and Mercury have gravity, but Mars is a bit heavier with about 0.38 times the gravity of Earth, while Mercury is even lighter with about 0.38 times the gravity of Earth. So, technically, they're both playing in the same gravity sandbox, just with different sized buckets.
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).
Their gravity is too weak to hold on to atmospheric gases.
