History of the Constellation Apus
This southern constellation cannot be viewed from any area of the earth more than 5 degrees north of the equator. Its name has been associated not only with the bird family called Paradisaeidae, it has also been associated with the Latin name Apis Indicia, meaning “Indian Bee”. “Apus” is a variation of the Latin root for bee, (as in Apiary). The consensus among many astronomers was that the name was originally should have been “Avis” meaning bird (as in Aviary).
In Bayer’s Uranometria,the constellation was referred to as Apis Indica,. In 1627Johannes Kepler, referred to it as Avis Indica in his Rudolphine Tables. To reduce the confusion of having two similar constellations, Bayer’s Avis Indica was renamed to Apus, and Apis, the constellation representing the bee, was renamed Musca, the fly by French astronomer Abbé Nicolas Louis de Lacaille.
Apus is the 67th constellation in size and it is set in the third quadrant of the southern hemisphere. You can see it at latitudes between +5° and -90°. Apus is bordered by these constellations: Ara, Chamaeleon, Circinus, Musca, Octans, Pavo and Triangulum Australe. , Circinus, Musca, Octans, Pavo and Triangulum Australe.
Due to its appearance only in the far southern sky, some associate the Apus constellation with the flower “The Bird of Paradise” native to South Africa. Strelitzia is a genus of five species of perennial plants known for their colorful winged appearance
