If each object has the same mass, which pair has the strongest gravitational attraction?

• The first, because it appears to weigh the most.
• The first, because the arrows are thickest.
• The  second, because it has an even balance of weight and distance.
• The first, because the objects are closest together.

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.
