Apus, Bird of Paradise Constellation Facts and Mythology

Apus Constellation Star Map

Apus (Pronounciation:A-pus, Abbrev:Aps, Latin:Apodis) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Apus takes up 206.327 sq. degrees of the night sky which equates to 0.5% of the night sky. Apus is the 67th largest in terms of size in the night sky.

The constellation name means Bird of Paradise . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by Pieter Dirkszoon Keyser and Frederick de Houtman years later.

There are 4 stars that make up the main constellation. The hipparcos satellite scanned and detailed 701 stars. There are 21 stars that can be seen with the naked eye in the constellation on a very clear night sky.

Apus is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Apus is a southern hemispheric constellation which means it can't be seen easily or at all from the northern hemisphere.

The distance to Apus is not calculable because all the stars that make up the constellation are at various distances. The best answer for distance to Apus is to calculate the average distance of the stars.

HIP 73871, Furthest Star

The furthest star that is located in the constellation is HIP 73871 and it is 54360.56 light years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.
