Apus

Apus is a small constellation close to the south celestial pole. It contains only two stars brighter than fourth magnitude.

It contains the globular cluster NGC 6101 and many faint galaxies, but no other deep sky objects that are easily seen.

Apus represents the bird of paradise, found in New Guinea. The name was given to this sky area by Keyser & de Houtman at the end of the sixteenth century.

Its name means “without feet” in Greek because the bird-of-paradise was once wrongly believed to lack feet.

In the Indian versions, apus is called ದೇವ ವಿಹಗ (Deva Vihaga).
