Musca

Musca (Latin: fly) is a small constellation in the deep southern sky. It was one of twelve constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman and it first appeared on a 35-cm (14 in) diameter celestial globe 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: bee) for two hundred years. Musca remains below the horizon for most Northern Hemisphere observers.

Many of the constellation's brighter stars are members of the Scorpius–Centaurus Association, a loose group of hot blue-white stars that appear to share a common origin and motion across the Milky Way. These include Alpha, Beta, Gamma, Zeta² and (likely) Eta Muscae, as well as HD 100546, a blue-white Herbig Ae/Be star that is surrounded by a complex debris disk containing a large planet or brown dwarf and possible protoplanet. Two further star systems have been found to have planets. The constellation also contains two Cepheid variables visible to the naked eye. Theta Muscae is a triple star system, the brightest member of which is a Wolf–Rayet star.

Apis (city)

Apis (Greek: Ἄπις, named for the god Apis), was an ancient seaport town (Polyb. Exc. Leg. 115) on the north coast of Africa, about 18 km west of Paraetonium, sometimes considered located within Egypt, and sometimes in Marmarica. Scylax (p. 44) places it at the western boundary of Egypt, on the frontier of the Marmaridae. Ptolemy (iv. 5. § 5) mentions it as in the Libyae Nomos; and so does Pliny the Elder, who calls it nobilis religione Aegypti locus (v. 6, where the common text makes its distance west of Paraetonium 72 Roman miles, but one of the best manuscripts gives 12, which agrees with the distance of 100 stadia in Strabo, xvii. p. 799).

This city should not be confused with the Apis described by Herodotus (ii. 18), the ancient Yamu, capital of the 3rd nome of Lower Egypt, currently occupied by the modern-day village of Kom el-Hisn.
