Camelopardalis // is a large but faint constellation in the northern sky. The constellation was introduced in 1612 (or 1613) by Petrus Plancius. Some older astronomy books give an alternative spelling of the name, Camelopardus.
First attested in English in 1785, the word camelopardalis comes from Latin, and it is the romanisation of the Greek "καμηλοπάρδαλις" meaning "giraffe", from "κάμηλος" (kamēlos), "camel" + "πάρδαλις" (pardalis), "leopard", due to its having a long neck like a camel and spots like a leopard.
Although Camelopardalis is the 18th largest constellation, it is not a particularly bright constellation, as the brightest stars are only of fourth magnitude. In fact, it only contains four stars above magnitude 5.0.
- α Cam is a blue-hued supergiant star of magnitude 4.3, 5000 light-years from Earth. Its distance is unusual for a naked-eye star.
- β Cam is the brightest star in Camelopardalis with an apparent magnitude of 4.03. This star is a double star, with components of magnitudes 4.0 and 8.6. The primary is a yellow-hued supergiant 1000 light-years from Earth.
- 11 Cam is a star of magnitude 5.2, 650 light-years from Earth. It is very close to magnitude 6.1 12 Cam, also 650 light-years from Earth, but the two stars are not a true double star because of their separation.
- Σ 1694 (Struve 1694, 32 Cam) is a binary star 300 light-years from Earth. Both components have a blue-white hue; the primary is of magnitude 5.4 and the secondary is of magnitude 5.9.
- CS Cam is the second brightest star, though it has neither a Bayer nor a Flamsteed designation. It is of magnitude 4.21 and is slightly variable.
In 2011 a supernova was discovered in the constellation.
Camelopardalis is in the part of the celestial sphere facing away from the galactic plane. Accordingly, many distant galaxies are visible within its borders. NGC 2403 is a galaxy in the M81 group of galaxies, located approximately 12 million light-years from Earth with a redshift of 0.00043. It is classified as being between an elliptical and a spiral galaxy because it has faint arms and a large central bulge. NGC 2403 was first discovered by the 18th century astronomer William Herschel, who was working in England at the time. It has an integrated magnitude of 8.0 and is approximately 0.25° long.
NGC 1502 is a magnitude 6.9 open cluster about 3,000 light years from Earth. It has about 45 bright members, and features a double star of magnitude 7.0 at its center. NGC 1502 is also associated with Kemble's Cascade, a simple but beautiful asterism appearing in the sky as a chain of stars 2.5° long that is parallel to the Milky Way and is pointed towards Cassiopeia. NGC 1501 is a planetary nebula located roughly 1.4° south of NGC 1502.
NGC 2655 is a small galaxy. IC 342 is one of the brightest two galaxies in the IC 342/Maffei Group of galaxies. The dwarf irregular galaxy NGC 1569 is a magnitude 11.9 starburst galaxy, about 11 million light years away.
MS0735.6+7421 is a galaxy cluster with a redshift of 0.216, located 2.6 billion light-years from Earth. It is unique for its intracluster medium, which emits x-rays at a very high rate. This galaxy cluster features two cavities 600,000 light-years in diameter, caused by its central supermassive black hole, which emits jets of matter. MS0735.6+7421 is one of the largest and most distant examples of this phenomenon.
Tombaugh 5 is a fairly dim open cluster in Camelopardalis. It has an overall magnitude of 8.4 and is located 5,800 light-years from Earth. It is a Shapley class c and Trumpler class III 1 r cluster, meaning that it is irregularly shaped and appears loose. Though it is detached from the star field, it is not concentrated at its center at all. It has more than 100 stars which do not vary widely in brightness, mostly being of the 15th and 16th magnitude.
The Space probe Voyager 1 is moving in the direction of this constellation, though it will not be nearing any of the stars in this constellation for many thousands of years, by which time its power source will be long dead.
Camelopardalis was created by Petrus Plancius in 1613 to represent the animal Rebecca rode to marry Isaac in the Bible. One year later, Jakob Bartsch featured it in his atlas. Johannes Hevelius gave it the official name of "Camelopardus" or "Camelopardalis" because he saw the constellation's many faint stars as the spots of a giraffe.

The giraffe's body consists of the quadrangle of stars α Cam, β Cam, BE Cam, and γ Cam: α Cam and β Cam being of the fourth magnitude. The stars HD 42818 (HR 2209) and M Cam form the head of the giraffe, and the stars M Cam and α Cam form the giraffe's long neck. Stars β Cam and 7 Cam form the giraffe's front leg, and variable stars BE Cam and CS Cam form the giraffe's hind leg.
