how gravity affects other planets

Gravity is the force that keeps people and animals on earth. It is also the force that keeps all the planets in orbit with the sun.

Gravity on earth is normal and easy to move with because the force from the moon is at a perfect distance from earth so if the moon was to blow up or take great damage in some way ,Earth would
suffer a dramatic gravity break down which in turn would come great damage to all living things
on earth.

If you were on a smaller planet like Mercury, you would be much lighter then you were on earth,usually the bigger the planet the more gravity it has which in turn makes you jump in to the sky of the smaller planet , smaller planets have less gravity because they don't need as much gravity as the bigger planet.

The gravitational pull is the force that pulls every thing to to the center of the universe and what keeps stars light years away from each other,if there was no gravitational pull on the stars there would be billions of giant balls of fire floating around our universe.

So if there was no gravity earth would either Fri or freeze to death because we would either be to far away from the sun or to close to the sun.

Gravity is important to planets and living things because it is the force that keeps them in line with the sun.
