It can be seen at latitudes between +85° and -75° and is best visible at 9 p.m. during the month of January. It is a dark nebula which is part of the Musca molecular cloud. Its name means “the fly” in Latin. It was a star originally 1.5 to 2 times as massive as our Sun. History of the constellation from Star Names , 1889, Richard H. Allen This title generally is supposed to have been substituted by La Caille, about 1752, for Bayer's Apis , the Bee; but Halley, in 1679, had called it Musca Apis ; and even previous to him, Riccioli catalogued it as Apis seu Musca . Musca does not contain any formally named stars. It is most easily found by first identifying the Southern Cross, then looking immediately south to a group of third- and fourth-magnitude stars. [36] It consists of a spectroscopic binary system composed of the Wolf–Rayet star (spectral type: WC5 or 6) and an O-type main-sequence star (spectral type: O6 or O7) that orbit each other every 19 days and a blue supergiant (spectral type: O9.5/B0Iab) set about 46 milliarcseconds apart from them. [65] Around five light-years across, it is located around 3400 light-years away.[12]. Constellation in the southern celestial hemisphere, This article is about the southern constellation. Lambda Muscae has an apparent magnitude of 3.68 and is the fourth brightest star in Musca constellation. Musca belongs to the Johann Bayer family of constellations, along with Apus, Chamaeleon, Dorado, Grus, Hydrus, Indus, Pavo, Phoenix, Tucana and Volans. Musca Constellation Map, by IAU and Sky&Telescope magazine, Musca was one of the 12 constellations introduced by the Dutch navigators Keyser and de Houtman during their expeditions to the East Indies in the late 16th century. It has an apparent magnitude of 4.11 and is approximately 302 light years distant. These include the Big Dipper and Little Dipper. The stars are similar in size and appearance. Theta Muscae is a triple star system, the brightest member of which is a Wolf–Rayet star. It has a planet (HD 111232 b) around 6.8 times the mass of Jupiter that has an orbital period around 1143 days. Musca depicts the common fly named by a Dutch explorer in 1500s. Musca or The Fly is one of the 88 constellations modern astronomers have divided the sky into. Today, there are 88 recognized constellations, each with their own story. The black hole in Nova Muscae 1991 has seven times the Sun’s mass, while the companion star has three-quarters of the Sun’s mass and one third of the Sun’s luminosity. [13] The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined by a polygon of six segments. Another tale says that Orpheus was murdered and then placed into the sky as a swan next to his lyre (the constellation Lyra, also in the drawing above). The two stars orbit each other every 505 days. Covering 138 square degrees and 0.335% of the night sky, it ranks 77th of the 88 constellations in size. [55] LP 145-141 is a white dwarf located 15 light-years distant—the fourth-closest to the Solar System. [49] HD 112410 is a yellow giant of spectral type G8III located around 439 light-years distant. Musca was one of the 12 constellations introduced by the Dutch navigators Keyser and de Houtman during their expeditions to the East Indies in the late 16th century. Small patterns of stars within a constellation are called asterisms. A nearby star of magnitude 13 may or may not be a companion star. [12] Lying south-southeast of Acrux in neighbouring Crux is Alpha Muscae. The nebula was discovered by Annie Jump Cannon and Margaret W. Mayall in the early 20th century, while they were working on an extended Henry Draper Catalogue. Pisces is a constellation of the zodiac.Its vast bulk – and main asterism viewed in most European cultures per Greco-Roman antiquity as a distant pair of fishes connected by one cord each that join at an apex – are in the Northern celestial hemisphere.Its name is the Latin plural for fish. The globular cluster NGC 4372 near Gamma Muscae is fainter and likewise partially obscured by dust, but spans more arc minutes. NGC 4372 is a globular cluster in Musca. [52] A gap exists between 4 and 13 AU, which appears to contain a large planet around 20 times the mass of Jupiter,[54] although further examination of the disk profile indicates it might be a more massive object such as a brown dwarf or more than one planet. Musca has several notable stars and deep sky objects, among them Nova Muscae 1991, the binary system with a black hole, the Spiral Planetary Nebula (NGC 5189), the Hourglass Nebula (MyCn 18), the globular clusters NGC 4833 and NGC 4372 and the Dark Doodad Nebula. HD 103079 is a binary star with a combined stellar classification of B4V, matching the spectrum of a blue-white main sequence dwarf. The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603. In the case of an X-ray nova, the flow of gas is quite slow and thin, and the disk around the black hole stays relatively cool. The stars have an orbital period of about 194 years. It has an apparent magnitude of 13 and is approximately 8,000 light years distant from Earth. [35], Theta Muscae is a triple star system thought to be around 7,500 light-years distant. Many of the constellation's brighter stars are members of the Scorpius–Centaurus Association, a loose group of hot blue-white stars that appears to share a common origin and motion across the Milky Way. You can easily improve your search by specifying the number of letters in the answer. [38] The system ranges from apparent magnitude 8.17 to 8.75 over around 1.4 days. In addition, Apus has no Messiers, meteor showers or stars with known planets. I.
