Answer the following question given this paragraph: As you can see in this NASA photo, Earth is tiny compared with the massive sun. The sun's gravity is relatively strong because the force of gravity between two objects is directly proportional to their masses. Gravity between the sun and Earth pulls Earth toward the sun, but Earth never falls into the sun. Instead, it constantly revolves around the sun, making one complete revolution every 365 days. Q: The sun's gravity is relatively strong because the force of gravity between two objects is directly proportional to their what? Choices: - tissues - Liquids - rocks - masses A:
masses
