Question

Quizplus · Accepted Answer

A circumpolar star is a star that always remains above the horizon for an observer at a certain latitude. It appears to rotate around the celestial pole and does not rise or set. Therefore, option C is the correct answer. Option A is partially correct as circumpolar stars are close to the celestial pole, but it does not specify if it is the north or south celestial pole. Option D is incorrect as all stars make a daily circle around the celestial sphere. Option E is also incorrect as not all circumpolar stars are visible from the Arctic or Antarctic circles as it depends on the observer's latitude.
