Mercury has less mass than Earth does, and gravity varies in direct proportion to mass.
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.
The moon has less mass than does Mars and therefore has less gravity at its surface.
Mercury, Venus, and Mars.
Your weight, or any objects weight, is a function of your mass and the local gravitational force. Planets such as Mars and Mercury, or even the moon have much lower gravity, since these bodies are smaller and less massive. So your weight will be less, though your mass will remain the same. I will still be a 100kg man (my mass), but on Mercury I will weigh 38kg.
While Mercury is denser than Mars it is also smaller, making it less massive.
Why does Mercury and Mars have less gravity than Earth because they both have less mass than does the Earth.
Mercury has less mass than Earth does, and gravity varies in direct proportion to mass.
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.

Mercury, Venus, Mars
Actually, the idea that Pluto had about the same mass as Mars is outdated. It is now known that Pluto has less than 2% the mass of Mars, and therefore has less gravity.
Of the 8 planets, Jupiter has most mass. Venus is 6th in the list. Only Mars and Mercury have less mass. The full list, from biggest mass to smallest mass, is : Jupiter, Saturn, Neptune, Uranus, Earth, Venus, Mars, Mercury.

No, it has much less mass.
