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

If the distance between Mercury and the Sun were increased, what could be done to maintain the same gravitational force of attraction between Mercury and the Sun?

• Decrease the masses of Mercury and the Sun
• Decrease Mercury’s speed of orbit around the Sun
• Increase the masses of Mercury and the Sun
• Increase Mercury’s speed of orbit around the Sun
