DescriptionThe Chameleon was created by Dutch navigators Keyser and de Houtman in the 1590s to fill the southern skies with creatures encountered during their tropical voyages. The tiny lizard known for changing color was a natural choice for a region of sky that is equally inconspicuous — the constellation contains no star brighter than magnitude 4. It sits near the south celestial pole and contains the Chamaeleon molecular cloud complex, an active stellar nursery where new stars are currently forming, about 520 light-years away. The brightest star, Alpha Chamaeleontis, is a white star about 64 light-years distant.
