What role did gravity play in the formation of the planets?

A.

The gravitational forces inside small asteroids pushed outward, causing the asteroids to swell to the size of planets.

B.

Planet-sized bodies passing by the solar system were pulled in by Earth's gravity and fell into orbit around the Sun.

C.

The gravity of the Sun was too weak to hold it together, and large pieces of the Sun broke off to form the planets.

D.

Gravitational forces brought together several moon-sized bodies, called planetesimals, to form larger bodies that became planets.

    Your answer would be D.

    If an object has mass, it has gravity, and the more mass it has, the stronger its gravity. During the formation of planets, essentially, various matter and elements pulled and fused together (because of the gravity), forming planetesimals.
