How can you if a particular star is circumpolar from a certain latitude?

To determine if a star is circumpolar from a certain latitude, you can compare the star's declination to the observer's latitude. A star is circumpolar if its declination is greater than or equal to the observer's latitude. For example, if you are at a latitude of 60°N, any star with a declination of +60° or higher will be circumpolar, meaning it never sets below the horizon. This can be visually confirmed by observing the star's position in the sky over time; circumpolar stars will appear to move in circles around the North or South celestial pole without dipping below the horizon.
