The Pleiades (/ ˈ p l iː. ə d iː z, ˈ p l eɪ-, ˈ p l aɪ-/), [8] [9] also known as Seven Sisters and Messier 45, is an asterism of an open star cluster containing young B-type stars in the northwest of the constellation Taurus.
The Pleiades are a volcanic group in northern Victoria Land of Antarctica. It consists of youthful cones and domes with Mount Atlas/Mount Pleiones, a small stratovolcano formed by three overlapping cones, being the dominant volcano and rising 500 m (1,600 ft) above the Evans Névé plateau.
Positions on the celestial sphere are often expressed using two coordinates: declination and sidereal hour angle, which are similar to latitude and longitude on the surface of the Earth. To define declination, the Earth's equator is projected out to the celestial sphere to construct the celestial equator , and declination is measured in degrees ...
Atlas is a triple star system, with the inner pair orbiting in under a year and the outer star orbiting in 260 years. The outer star, component Ab (sometimes component B, such as in CCDM and SIMBAD [16]), has been resolved at a distance of 0.784″ from the unresolved spectroscopic binary.
Maia is the fourth-brightest star in the Pleiades open star cluster (Messier 45), after Alcyone, Atlas and Electra. It is surrounded by one of the brighter reflection nebulae within the Pleiades, designated NGC 1432 and sometimes called the Maia Nebula .
23 Tauri is the star's Flamsteed designation.The name Merope originates with Greek mythology; she is one of the seven daughters of Atlas and Pleione known as the Pleiades.In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) [21] to catalog and standardize proper names for stars.
Electra / ə ˈ l ɛ k t r ə /, [11] designated 17 Tauri, is a blue-white giant star in the constellation of Taurus located approximately 400 light years away. It is the third-brightest star in the Pleiades open star cluster (), visible to the naked eye with an apparent magnitude of 3.7.
Alcyone / æ l ˈ s aɪ ə n iː /, [11] designated η Tauri (Eta Tauri, abbreviated Eta Tau, η Tau), is a star in the constellation of Taurus.Approximately 440 light-years from the Sun, it is the brightest star in the Pleiades open cluster, which is a young cluster, around 100 million years old.
