The force that pulls two objects towards each other;

the greater the mass of an object, the greater the attraction; the further apart the objects,

the weaker the attraction.

Why do planets orbit the Sun?

• The Sun is the only celestial object that has a gravitational pull.

• The Sun’s chemical composition makes it attract planets.

• Only celestial bodies that emit light, like the Sun, can be at the center of an orbit.

• The Sun is the most massive object in our solar system, so it exerts the greatest gravitational pull.
