No. Gravity depends on only two factors: mass and distance from the center of mass of the object. Gravity increases in proportion to the mass of the object and decreases in proportion tot he square of the distance from it. So doubling the mass doubles the gravity. Doubling distance cuts gravity to one quarter the original value.

So, if you were to compress Earth to a smaller size without decreasing its mass, gravity where the surface originally was would remain the same. Gravity at the surface in its new position, closer to the center of mass would actually increase.

Would the gravity on the planet Mercury squash someone?

No. The gravity on Mercury is less than half that of Earth.


Does mars have 62 times less gravity than earth?

No. The gravity on Mars is about 38% that on Earth. So Mars has about 62 percent less gravity.


Does the moon or Mars have less gravity?

The moon has less mass than does Mars and therefore has less gravity at its surface.


Which planet has less gravity earth or mars?

Mars has less gravity.


Why is there less or no gravity on the moon then there is on earth?

There is gravity on the moon. It is about on sixth what it is on Earth. This is because the moon has less mass than Earth does.


Is gravity on earth greater or less then gravity on mercury?

The gravity on Earth is stronger than the gravity on Mercury.


What is the gravity on mars like?

The gravity on Mars is about 38% of the gravity on Earth. This means that objects weigh less on Mars compared to Earth.


Is there gravity on Mars less earth?

Yes. The effects of gravety on Mars are less than on Earth. Mars has 37.6% of Earth's gravity.


How much less is the Moon's gravity than that of the earth's?

Since the Moon's gravity is 1/6 that of Earth, the Moon's gravity is 5/6 less than that of Earth.


Why does Mercury and Mars have less gravity than Earth?

Why does Mercury and Mars have less gravity than Earth because they both have less mass than does the Earth.


Is the Moon's gravity less than the earth's gravity?

Yes, it is significantly less.


Does the moon have less gravity then the earth?

Yes. The moon is 1/4 the size of Earth, so the moon's gravity is much less than the earth's gravity, 83.3% (or 5/6) less to be exact.
