Which of the following situations describes an acceptable path for a body gravitationally bound to the Sun?

Question

Quizplus · Accepted Answer

According to Kepler's laws of motion, a body gravitationally bound to the Sun will follow an elliptical path with the Sun at one focus. Therefore, the only acceptable path among the given options is the long ellipse with the Sun at one focus (choice C). A parabolic path (choice A) implies that the body is not bound to the Sun and will leave the solar system. A circular path (choice B) implies that the body is not in a gravitationally bound orbit and will require a constant external force to maintain its motion, which is not the case for natural planets and other bodies. A long ellipse with the Sun at its center (choice D) violates Kepler's law that the Sun should be at one focus of the elliptical orbit.
