Question 1556Navigation General

The correct answer is C) rotation. The spinning of a celestial body, such as a planet or star, about its own axis is known as rotation. This is a fundamental motion of celestial bodies and is distinct from other motions like revolution (the orbit of a body around another body) or nutation (the slight wobble in the axis of rotation of a body). The other answer choices are incorrect because: A) Nutation refers to a slight wobble in the axis of rotation, not the rotation itself. B) Revolution refers to the orbital motion of a body around another body, not the spinning motion. D) "Space motion" is not a recognized term for any specific type of celestial motion.
