Article History

Chamaeleon, constellation in the southern sky at about 11 hours right ascension and 80° south in declination. Its brightest star is Alpha Chamaeleontis, with a magnitude of 4. This constellation was invented by Pieter Dircksz Keyser, a navigator who joined the first Dutch expedition to the East Indies in 1595 and who added 12 new constellations in the southern skies. It is named after the chameleon, the lizard that can change its skin colour to blend in with its surroundings.
