What makes an object have stronger gravitational pull?
it's size: if the object is large
it's distance from another object
it's mass: if it's heavier

The gravitational attraction between two objects would increase if both masses are –
increased, and the distance between them is increased.
increased, and the distance between them is decreased.
decreased, and the distance between them is decreased.
decreased, and the distance between them is increased.
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.
