Catalog of Circumpolar Stars
(Groombridge)
(list of over 4000 stars in northern part of the sky)
The Catalog of Circumpolar Stars
is a publication of a list of northern stars, assembled by Stephen
Groombridge during the first third of the 1800s.
Circumpolar stars are stars that never fall below the horizon,
i.e., never set as does the Sun and Moon. These are
stars toward the nearer pole, e.g., the north pole if you are in
the northern hemisphere. Exactly which stars are circumpolar depends
upon the latitude from which you are observing: the further poleward
you are, the larger the region of the celestial sphere has this
quality: from the north or south pole you can see half the sky,
and none of the stars set. From the equator, you can see the whole
sky, but the stars set daily. Groombridge was observing roughly
from London, where nearly the northern-most 40% of the celestial
sphere is circumpolar.
