Camelopardalis (abbr. Cam, gen. Camelopardalis)
The Giraffe; a large, relatively barren constellation near the north celestial
pole, lying between Ursa Major and Cassiopeia.
Only three of its stars, Beta, 7 Cam, and Alpha, reach fourth magnitude.
Alpha is a notably remote and intrinsically luminous O
star (visual magnitude 4.26, absolute magnitude -7.38, spectral type
O9Ia, distance 6,940 light-years). See below for details of some of the
constellation's interesting deep sky objects.

||A small planetary, just south of 32 Cam,
that looks like a star slightly out of focus. Magnitude 11.6; diameter
18"; distance 9,000 light-years; R.A. 12h 33.11m, Dec. +82°
||A tiny but striking object containing
about 15 stars. The brighter members are in a triangular arrangement
while the fainter ones lie in a circular background. Magnitude 5.7;
diameter 5.7'; R.A. 04h 7.7m, Dec. +62° 20'
||A spiral galaxy readily seen in small
telescopes at low power and even visible with a good pair of binoculars
as a hazy glow. In larger instruments it appears as a fat cigar-shape.
It is an outlying member of the M81 Group.
Magnitude 8.4; size 18' × 11'; distance 12 million light-years;
