Camelopardalis, Latin for giraffe, is the name of a large but faint northern constellation first recorded by Jakob Bartsch in 1624, but probably created earlier by Petrus Plancius. ... Right ascension (RA; symbol α: Greek letter alpha) is the astronomical term for one of the two coordinates of a point on the celestial sphere when using the equatorial coordinate system. ... In astronomy, declination (dec) is one of the two coordinates of the equatorial coordinate system, the other being either right ascension or hour angle. ... // Headline text HEY!! HOW ARE YOU ALL??

The binary system is classified as a white A-type main sequence dwarf with a mean apparent magnitude of +5.20. Both component stars are detached main sequence stars which do not fill their Roche lobes. Because the components regulary eclipse each other, 31 Camelopardalis is classified as a variable star and its brightness varies from magnitude +5.12 to +5.29 with a period of 2.93 days, which is the orbital period of the binary. In astronomy, stellar classification is a classification of stars based initially on photospheric temperature and its associated spectral characteristics, and subsequently refined in terms of other characteristics. ...
