What characteristic defines Circumpolar Stars for an observer in the Northern Hemisphere?
Answer
These are stars located close enough to the celestial pole that they never dip below the observer's horizon and are always visible.
Circumpolar Stars represent a specific subset of visible stars defined by their proximity to the celestial pole relative to the observer's latitude. For a fixed observer, particularly in the Northern Hemisphere looking toward the North Star, circumpolar stars are those whose paths are so small and so close to the pole that they never intersect the horizon. Consequently, these stars are visible throughout the entire night, tracing constant, small circles around the North Star. When viewed from above the North Pole, their apparent motion is counter-clockwise.
