Which of the following explains why the Earth orbits the sun rather than the sun orbiting the Earth?
A. The force of Earth's gravity pulling on the sun has a smaller
magnitude than the force of the sun pulling on the Earth.
B. Even though the sun is pulled toward the Earth, the force is
opposed by forces from the gravity of the other planets.
C. While the Earth is pulled toward the sun with a gravitational force,
the sun is not pulled toward the Earth by a gravitational force.
D. Earth has a much smaller mass, so the gravitational force
accelerates the Earth much more than it accelerates the sun.
