 Invention of Apus

Apus lies near the south celestial pole, to the south of Centaurus. It is not easy to identify and contains few objects of note. It is one of the constellations invented at the end of the 16th century by the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman, and represents a new Guinea bird of paradise. Its brightest star is Alpha Apodis, magnitude 3.8.

 Best Viewed Objects/Stars

Delta Apodis
 A wide double star, easily divided with binoculars. The two stars are of magnitude 4.7 and 5.3. They are both red giants but are estimated to lie at different distances from us, 760 and 660 light-years respectively, so they probably form an optical double rather than a genuine binary.
