Yes. Earth is about 6.5 times larger than Mars and has more mass.
No. Mars is a little more than a tenth the mass of Earth.
No, Mars has a greater mass than Venus. Mars has a mass of about 0.107 times that of Earth, while Venus has a mass of about 0.815 times that of Earth.
No, because it is only slightly larger than Earth's core, but is off an almost equal density.
Strictly speaking, no. Earth has stronger gravity because it has more mass than Mars does. Size is a measure of how much space an object occupies. Mass is a measure of how much matter an object contains.
There is no direct connection between the mass of a planet and the number of moons it has. Mars is less massive than Earth but has twice as many moons as does Earth. Jupiter is more massive than either Mars of Earth and has many more moons that either of them.
Really small. 3.68x10^37% in scientific notation.
No. Mars is a little more than a tenth the mass of Earth.
There is no particular reason: some planets have more mass than others.
Earth is more massive than Mars and therefore has greater gravity.
The gravitational force exerted at the surface (and above the surface) of Mars is weaker than that here on Earth. The reason: Mars has less mass than earth.
Because Mars is a lot less massive than the Earth. The surface gravity depends on the mass of the planet you are standing on, and since Mars is lighter the surface gravity there will be less than here on Earth.The gravitational force between two objects depends on their mass and the distance between their centers of mass. Mars has a smaller radius than the Earth (which would tend to increase the gravitational force), but it has a much smaller mass than the Earth (which tends to decrease the gravitational force). Combining the two factors, it works out that the surface gravity of Mars is about one-third that on Earth.
Earth is larger than Mars in terms of both diameter and mass. Earth has a diameter of about 12,742 kilometers, while Mars has a diameter of about 6,779 kilometers, making Earth about 1.9 times larger than Mars. Earth's mass is also greater than Mars', with Earth being about 10 times more massive than Mars.
No, Mars has a greater mass than Venus. Mars has a mass of about 0.107 times that of Earth, while Venus has a mass of about 0.815 times that of Earth.
