Apus
Origin
Apus is a small, relatively faint constellation in the far southern sky, within 7 degrees of the south celestial pole. Apus represents the bird of paradise and means “without feet”. Apus first appeared on a celestial globe created by Petrus Plancius in 1598.
Bright Stars
The brightest star, Alpha Apodis, shines at a magnitude of 3.8 and is an orange giant. Beta Apodis is also an orange giant shining at a magnitude of 4.2. Delta Apodis is a double star with the two components separated by 103 arcseconds. This is easy to split in binoculars but a naked eye challenge!
