• the gravity of both Earth & Sun increases

• the gravity of the Earth & Sun decreases

• no one is sure because you cannot increase the size of the Earth & Sun

• all of the above

Which of the following describes a role of gravity in the formation of our solar system?

• In the early stages of solar system formation, a fragment of an interstellar cloud of dust and gas collapsed and began rotating under the influence of gravity.

• The eight planets were originally orbiting a nearby star, and the Sun's gravity pulled those planets into orbit around the Sun.

• Gravity caused small particles in the rotating solar nebula to stick together and form larger particles. This process repeated itself, forming larger and larger particles that eventually became planets.

• The combined gravities of the planets pulled the Sun away from a nearby star cluster and into the center of the solar system.
