The Caméléon is a Constellation of the Southern hemisphere. It is about several star S pale which one connected between them to form a chameleon far from perceptible.

It is near the celestial south pole. Its the most brilliant star is α  Chameleontis .

History

This constellation was Dutch proposed by the navigators Pieter Dirkszoon Keyser and Frederick de Houtman at the end of XIVe century and was presented by the Astronome Johann Bayer in his stellar atlas Uranometria in 1603.

It draws probably its name from the “exoticism” of the animal, Johann Bayer having surely wanted to recently place in the skies a known animal of the European and that one found only in the southern hemisphere.

α  Chamaeleontis

The most brilliant of constellation, logically named star α  Chamaeleontis, reaches only the Magnitude connect 4,05, which makes a particularly weak luminary of it. It is about a white giant star, which is relatively not very current, rather near (63,5 light-years).

δ  Chamaeleontis

The most interesting star of the constellation of the Chameleon is δ  Chamaeleontis. It is about a star doubles visual, because the two elements are not in fact not dependant and even distant one of the other 10 light-years.

Most brilliant (and most distant, distant 364 light-years) is δ ²   Chamaeleontis. It is about a blue star.

δ1  Chamaeleontis is itself binary. The couple, composed of two stars rather similar oranges (magnitude 6,1 and 6,3), is distant 354 light-years. These two stars produce a magnitude 5,46 together.

The contrast of the colors between δ1 and δ ² in fact an object very interesting to observe.

Other stars

Among principal stars of the constellation, two others are double: ε  Chamaeleontis (magnitudes 5,4 and 6,0) and θ  Chamaeleontis (4,34 and 12,44).

Celestial objects

The constellation of the Chameleon presents the Nébuleuse planet gear NGC 3195, a remarkable object luminous which seems a luminous disc of the same apparent size as Jupiter.
