Question 1564Navigation General

You are correct, the answer is B) motion of a celestial body in its orbit. The term "revolution" in the context of celestial mechanics refers to the motion of a celestial body, such as a planet or a moon, as it orbits around another body, such as the Sun or a planet. This orbital motion is distinct from the spinning or "rotation" of a celestial body about its own axis, which is described by option C. The other options are incorrect because they do not accurately describe the meaning of "revolution" in this context. Option A refers to the motion of celestial bodies relative to the stars, which is not the primary definition of "revolution." Option D describes the "wobbling" of the Earth's axis, which is a different phenomenon known as precession, not revolution.
