Star or objects that are close enough to the pole so that they never set from your particular latitude.
denotes an object near a celestial pole that never dips below the horizon as Earth rotates.
Stars that appear close enough to one of the celestial poles that they seem to circle around the pole above the horizon. These stars are visible year-round.
when an object is close enough to either the north celestial pole or south celestial pole (within an angular distance = observer's latitude) such that the object never moves below an observer's horizon or never rises above the horizon as the Earth rotates.
(of a celestial body) continually visible above the horizon during the entire 360 degrees of daily travel; "a circumpolar star"
An object that does not set from its observer's latitude.
The stars or constellations that are closer to the celestial pole than the horizon and therefore never set
Ranging around either pole.
appearing to circle around Polaris
A celestial object positioned near a celestial pole such that, from your latitude, it never goes below the horizon.
Those stars that are so far north (or so far south, in the southern hemisphere) that they do not set when viewed from from certain latitudes.
A circle of sky which is permanently above the observer's horizon, with stars that never set. (Literally, "around the pole".) This is a function of the observer's latitude; e.g. in Edmonton, with a latitude of 54° N., the North Star, Polaris, appears permanently fixed 54° above the northern horizon; all stars within 54° of Polaris do a daily wheel around it without ever setting. There is a commensurate 54° circle of the southern sky which never rises.
This is a region of the sky that is always visible round the celestial pole closest to the observer. An object in this area will therefore never set, at any time of the night (or day of course) and can be observed at any time of the year e.g. the Plough asterism is in the circumpolar region from the UK and can be seen in all four seasons, Orion is not circumpolar and so can only be observed for part of the year.
