Any star whose declination is higher than (90 - your latitude) will be "circum-polar", meaning that the star will never appear to set.
The star Alkaid, one of the handle stars in the Big Dipper, has a declination of 49 degrees. If your latitude is 90-49=41 N, then the star Alkaid will never go below the horizon.
displayed on a nautical chart that shows the amount and direction of the magnetic declination for a specific location. It is used by navigators to correct compass readings and determine true north.
