Question

Quizplus · Accepted Answer

Axial precession refers to the slow motion of Earth's axis where it wobbles like a top, completing a full cycle in about 26,000 years. This motion causes changes in the position of the stars in the night sky over time. Ptolemaic motion, occultation, perturbation, and retrograde motion are all different astronomical terms and phenomena unrelated to axial precession.
