Mercury has less mass than Mars primarily due to its smaller size and different composition. Mercury is the smallest planet in the solar system, with a diameter of about 4,880 kilometers, while Mars has a diameter of about 6,779 kilometers. Additionally, Mercury is primarily composed of metal and rock, resulting in a higher density, but its overall volume and mass remain lower compared to Mars, which has a more substantial atmosphere and surface features. Therefore, despite its density, Mercury's smaller size leads to a lower total mass.
Mercury has less mass than Earth does, and gravity varies in direct proportion to mass.
Mercury has much less mass than Mars primarily due to its smaller size and composition. Mercury is the smallest planet in the solar system and has a metallic core with a thin silicate mantle, while Mars is larger and has a more substantial mantle and crust made up of various minerals. The differences in their formation and the amount of material available in the early solar system also contribute to Mercury's lower mass compared to Mars. Additionally, Mars has a more significant gravitational influence, allowing it to retain a thicker atmosphere and more substantial surface features.
Among the inner planets, Earth has the greatest mass. It has a mass of approximately 5.97 x 10²⁴ kilograms, significantly more than that of Mercury, Venus, and Mars. Venus comes next in mass, followed by Mars and then Mercury.
Mercury, Venus, and Mars.
No, it has much less mass.
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.
The planets that have less mass than Earth are Mercury, Mars and Venus. The planets that have a lower average density than Earth are all of them; Earth is the most dense planet in our solar system.

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.
Mercury, Venus, and Mars.
No, it has much less 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.
