Musca the Fly- Southern Hemisphere
Musca
(Latin for "the fly") is a small constellation in the deep
southern sky. It was one of 12 constellations created by Petrus
Plancius from the observations of Pieter Dirkszoon Keyser and
Frederick de Houtman, and it first appeared on a celestial globe 35
cm (14 in) in diameter published in 1597 (or 1598) in Amsterdam by
Plancius and Jodocus Hondius.
The first depiction of this constellation in a celestial atlas was in
Johann Bayer's Uranometria of 1603. It was also known as Apis (Latin
for "the bee") for 200 years.
Lacaille
in 1776 renamed it to Musca Australis, the Southern Fly—Australis,
to its then counterpart the now discarded constellation of Musca
Borealis. The Australis part has now been discarded.
