The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined by a polygon of 26 segments. The recommended three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is "Tau". A ring-like galactic structure known as Gould's Belt passes through the constellation. Taurus is the only constellation crossed by all three of the galactic equator, celestial equator, and ecliptic.
The galactic plane of the Milky Way intersects the northeast corner of the constellation and the galactic anticenter is located near the border between Taurus and Auriga. As the orbital plane of the Moon and the planets lie near the ecliptic, they can usually be found in the constellation Taurus during some part of each year. This circle across the celestial sphere forms the apparent path of the Sun as the Earth completes its annual orbit. This constellation forms part of the zodiac and hence is intersected by the ecliptic. By late March, it is setting at sunset and completely disappears behind the Sun's glare from May to July. In late November-early December, Taurus reaches opposition (furthest point from the Sun) and is visible the entire night. Taurus is a large and prominent constellation in the northern hemisphere's winter sky, between Aries to the west and Gemini to the east to the north lies Perseus and Auriga, to the southeast Orion, to the south Eridanus, and to the southwest Cetus. The variable star T Tauri is the prototype of a class of pre-main-sequence stars. One of the closest regions of active star formation, the Taurus-Auriga complex, crosses into the northern part of the constellation. In the northeast part of Taurus is the supernova remnant Messier 1, more commonly known as the Crab Nebula. At first magnitude, the red giant Aldebaran is the brightest star in the constellation. Taurus hosts two of the nearest open clusters to Earth, the Pleiades and the Hyades, both of which are visible to the naked eye. The symbol representing Taurus is (Unicode ♉), which resembles a bull's head.Ī number of features exist that are of interest to astronomers. Its importance to the agricultural calendar influenced various bull figures in the mythologies of Ancient Sumer, Akkad, Assyria, Babylon, Egypt, Greece, and Rome. It is one of the oldest constellations, dating back to the Early Bronze Age at least, when it marked the location of the Sun during the spring equinox.
Taurus is a large and prominent constellation in the Northern Hemisphere's winter sky. Taurus ( Latin for "the Bull") is one of the constellations of the zodiac and is located in the northern celestial hemisphere. Visible at latitudes between + 90° and − 65°.īest visible at 21:00 (9 p.m.) during the month of January.
