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.
Gravity can be defined as the –
force of attraction between two or more masses.
friction created when two objects are in contact.
energy given off by stars due to nuclear reactions.
path an object follows as it moves through space.
