Chamaeleon is one of a dozen constellations introduced by Johann Bayer in 1603 for his star atlas Uranometria. Like most of these, Chameleon is far to the south. In fact, its stars are circumpolar to residents of the Southern Hemisphere. The asterism is supposed to represent a chameleon. Apparently the animal has changed itself into a rhomboid. There are only a handful of Bayer stars, and these are generally forth and fifth magnitude. There are a couple of binaries, a Mira-type variable, and one deep sky object of some interest.
