Circumpolar
Never setting: close enough to the celestial pole that, from your latitude, it circles the pole all night.
From latitude 40° north, every object with a declination above +50° is circumpolar — Ursa Major, Cassiopeia, the Double Cluster. The farther from the equator you live, the more of the sky never sets (and the more never rises).
In AstroPilot
Object pages say when something is circumpolar from your site.
