ध्रुवीय-तारा इसके अंग्रेजी अर्थ का उदाहरण

To determine absolute declinations or polar distances, it was necessary to determine the observatory's colatitude, or distance of the celestial pole from the zenith, by observing the upper and lower culmination of a number of circumpolar stars.

The telescope was then brought into the meridian by repeatedly timing the (apparent, incorrect) upper and lower meridian transits of a circumpolar star and adjusting one of the bearings horizontally until the interval between the transits was equal.

These circumpolar stars are now known as Kochab (Beta Ursae Minoris), in the bowl of Ursa Minor or, the Little Dipper, and Mizar (Zeta Ursae Majoris), in Ursa Major, at the middle of the handle of the Big Dipper.

"Circumpolar stars are a very good metaphor for the afterlife because when viewed, they never seem to set: they simply rotate around the pole star.
