1) An object with more mass has more gravitational pull.
2) The sun has more gravity than the Earth.
3) The gravitational pull of Earth causes the moon to orbit Earth.
4) The unbalanced force of gravity causes comets, meteors, and asteroids to collide with planets.
5) The force of gravity causes Earth to travel in a sideways path around the sun.
6) a. Most mass = Sun
b. Middle mass = Earth
c. Least mass = Moon
