Mars is much less massive that the Earth; its mass is about a tenth that of Earth, or abut 8.6 times as much as our Moon. Mars also has a lower average density than the Earth, partly because it it has more rock and less metal in comparison to the Earth, and partially because its weaker gravity has resulted in less compression of its interior.

Would a earthling feel heavier or lighter on the surface of mars?
As Mars is smaller than earth, and therefore has a lighter gravity, a person would feel lighter on Mars. In fact on Mars you would weigh half as much
What is Mars size compared with Earth?
one year on mars is equivalent to 780 earth days
Which planets are lighter than earth?
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.
What planet has evidence of erosion by water?
Earth and Mars
Does mars have stronger grtavity than earth or weaker?
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.

Why would you weigh 57 pounds on Mars if you weigh 150 on Earth?
Your weight depends on the gravity, and Mars, being a smaller/lighter planet has less gravitational pull than the earth.
What is Mars size compared with Earth?
one year on mars is equivalent to 780 earth days
Why Would you feel lighter on mars?
Mercury has less mass than Earth does, and gravity varies in direct proportion to mass.
Is there a safe gravity on Mars'?
Yes. You can walk on Mars (wearing adequate protective clothing of course) without much trouble. You will be lighter there than on Earth, so you will be able to jump higher.
What is the Gravity in Mars?
The equatorial gravity on Mars is 3.69 m/s2 or 0.376g (37% that of Earth). If you weighed 100 lbs on Earth you would weigh 37.7 lbs on Mars
Which planets are lighter than earth?

What is that new lighter song called?
Lighter - Eminem ft. Bruno Mars
What planet has evidence of erosion by water?
Earth and Mars
How is earth and Mars alike List 4 ways?
Earth and mars are totally different. Earth is green and blue. Mars is red & brown. WE live on earth and martitans live on Mars. Mars is not cool but earth is. Earth has living things mars doesnt.!!!!
Is mars smaller or larger than earth?
Smaller, Mars is about half the size of Earth
Why is Mars so slow at orbiting the Earth?
Mars does not orbit the Earth. Mars orbits the Sun, as does the Earth.
