What keeps all of the planets in the solar system from leaving their orbits around
the Sun? *

A: The repulsion of each planet's magnetic field keeps the planets in orbit.

B: The gravitational pull of the Sun keeps the planets from leaving their orbits.

C: The gamma, infrared, and radio waves being emitted from each planet create a path
for it to orbit the Sun.

CD: The gravitational pull of each planet provides just enough force to keep them apart
from one another but still in orbit around the Sun.
