The Sun has a greater mass than the planets.
The Sun has a greater mass than the planets.

Answer 1

"The Sun has a greater mass than the planets."

Reason: Gravity depends on mass; the Sun's much larger mass creates the dominant gravitational pull that keeps the planets in orbit (Newton's law of universal gravitation). The other statements don't explain why the Sun governs planetary motion.
