The constellation name means The Bear Driver . [10] Another myth associated with Boötes relates that he invented the plow and was memorialized for his ingenuity as a constellation. The first reference to the name Boötes comes from "The Odyssey" by Homer almost three millenia ago. There are not much in the way of galaxies in this region, an area of that size should contain about 10,000 Galaxy but so far there have only been about 60 discovered. All messages will be reviewed before being displayed. [41] It is ever so slightly variable, wavering by 0.003 of a magnitude from its average of 3.57. [13] Other galaxies include NGC 5008, a type Sc emission-line galaxy,[74] NGC 5548, a type S Seyfert galaxy,[75] NGC 5653, a type S HII galaxy,[76] NGC 5778 (also classified as NGC 5825),[77] a type E galaxy that is the brightest of its cluster,[78] NGC 5886,[79] and NGC 5888, a type SBb galaxy. There are three main meteor showers associated with the constellation Boötes, namely the January Boötids, the June Boötids, and the Quadrantids. There are 13 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. It is 219 light-years away[8] and has a luminosity of 58 L☉. [1] This influenced the name's etymology, derived from the Greek for "noisy" or "ox-driver". Izar, also known as Epsilon Boötis, is the second brightest star in the constellation of Boötes, after Arcturus, and one of the first telescopically observed binary stars. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. [90], On April 28, 1984, a remarkable outburst of the normally placid Alpha Bootids was observed by visual observer Frank Witte from 00:00 to 2:30 UTC. Boötes Constellation Map, by IAU and Sky&Telescope magazine, Boötes is traditionally depicted as a herdsman with two hunting dogs on a leash and a club in his other hand. One legend has him as the man who with his dogs Canes Venatici, chase the bears around the skies keeping the Earth rotating. The star’s traditional name is Muphrid, derived from the Arabic phrase for “the single one of the lancer.” It is also known as Saak. In the sky, Boötes follows Ursa Major around the pole. Seginus is relatively easy to identify because it is one of the stars that form the kite-shaped asterism that dominates the Boötes constellation. It is smaller than Jupiter, at 0.884 MJ and 0.962 RJ. Boötes has two bright galaxies. 1. Seginus lies in the vicinity of two spiral galaxies, NGC 5698 and PGC 51713. According to one version, he was a son of Demeter,[7] Philomenus, twin brother of Plutus, a plowman who drove the oxen in the constellation Ursa Major. (The “pe” stands for “peculiar emission.”) Approximately 36.7 light years distant, the star has a luminosity at least 110 times that of the Sun and a very high proper motion; it moves at 122km/s relative to the solar system. [40] The primary is 97 light-years away. However, this meteor shower is not known for its spectacular displays, nor does it occur every year. The following list contains the stars that make up the constellation. Arcas is raised by Maia, the mother of Hermes. Callisto was turned into a bear by a very angry Hera. He was the inventor of the plow, and upon his death, was placed in the stars. O Boötis has an absolute magnitude of 0.2. However, it has also been associated with three stars in Coma Berenices. The name Boötes comes from the Greek for word for ox-driver” or “herdsman”. It is also a member of the Local Fluff, or more precisely, the Local Interstellar Cloud, a 30-light-year-diameter interstellar cloud through which the entire solar system is currently moving. [6] Exactly whom Boötes is supposed to represent in Greek mythology is not clear. Though named for a star in Boötes, the Phi Bootid radiant has moved into Hercules. Most commonly, Boötes is taken to represent Arcas, son of Zeus and Callisto, daughter of the Arcadian king Lycaon. The shower period is a brief few hours in the morning. Seginus is located in the constellation Boötes. In another myth, Boötes is credited for inventing the plough, which prompted the goddess Ceres to place him in the heavens. The Epsilon Boötis star system consists of an orange giant star of spectral type K0 II-III, and a blue-white main-sequence star of spectral type A2 V. There are 18 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The neighboring constellations are Boötes… In the meantime Callisto had been transformed into a she-bear by Zeus's wife Hera, who was angry at Zeus's infidelity. Callisto roamed the woods until years later she met her son, who was now grown up. Boötes has one of the most active of meteor showers at the beginning of the solar year in January and is known as the Quadrantids. [48], Two of the brighter Mira-type variable stars in the constellation are R and S Boötis. The cloud is 30 light years across. For instance, typical galaxies such as the Milky Way would be represented as a peak with about the same footprint and height as the Empire State Building, while even a modestly sized void would represent a three-foot-deep hole that is three times as big as Manhattan. The secondary is itself an eclipsing variable star with a range of 0.6 magnitudes; its orbital period is 6.4 hours. The name Boötes comes from the Greek for word for ox-driver” or “herdsman”. The reason for the difference in name comes from the fact that the centre of activity used to be a now ignored constellation called Quadrans Muralis to the north of Boötes. Arcturus is believed to be an old disk star. [92] Its meteors are slow-moving, with a velocity of 15.1 km/s. Boötes /boʊˈoʊtiːz/ is a constellation in the northern sky, located between 0° and +60° declination, and 13 and 16 hours of right ascension on the celestial sphere. It is often listed as the fourth brightest star, behind Alpha Centauri, because the latter is a binary star with a combined magnitude of -0.27. The star names approved by the International Astronomical Union (IAU) are Alkalurops, Arcalís, Arcturus, Izar, Merga, Muphrid, Nekkar, Nikawiy, Seginus, and Xuange. This means that the star expands and contracts, changing its radius to maintain the spherical shape (radial pulsations), and some parts of its surface move inwards, while others simultaneously move outwards (non-radial pulsations). The primary is an orange giant of magnitude 5.0 and the secondary is a white star of magnitude 5.0. Dionysus was saddened by the death of his friend and decided to place Icarius among the stars. [80] NGC 5698 is a barred spiral galaxy, notable for being the host of the 2005 supernova SN 2005bc, which peaked at magnitude 15.3. 0. It has an apparent magnitude of 4.52. It is mandatory to procure user consent prior to running these cookies on your website. [40], An apparent magnitude 4.18 type A0p star,[13] Lambda Boötis is the prototype of a class of chemically peculiar stars, only some of which pulsate as Delta Scuti-type stars. Iota Boötis is a triple star with a primary of magnitude 4.8 and spectral class of A7,[13] a secondary of magnitude 7.5,[8] and a tertiary of magnitude 12.6. The quasar has a mass that is 800 times the solar mass of our Sun. It is a flare star, a type of variable star that shows dramatic increases in luminosity for a few minutes. ref:Wiki.

Comments may be merged or altered slightly such as if an email address is given in the main body of the comment. Its name is from the Arabic phrase for "club" or "staff". Arcturus is believed to a member of the 52-strong Arcturus Stream, a small group of stars that is moving perpendicularly through the plane of the Milky Way. Angry, they decided to murder him in his sleep. Sometimes Arcturus is depicted as leading the hunting dogs of nearby Canes Venatici and driving the bears of Ursa Major and Ursa Minor. Zeus rescued her, taking her into the sky where she became Ursa Major, "the Great Bear". Other objects on interest in Boötes includes NGC 5466, a globular star cluster consisting of thousands of stars; as well as several galaxies including NGC 5248, NGC 5676, NGC 5008, NGC 5886, NGC 5888, and NGC 5698. Another myth linked to Boötes has many variations. Its host star is a magnitude 7.88 G5-type star, 98.2 parsecs from Earth. Boötes (Pronounciation:Boo-oh-teas, Abbrev:Boo, Latin:Bootis) is one of 88 constellations that the night sky is divided into. Its planet, HD 132563B b, was discovered in 2011 by the radial velocity method. HAT-P-4, the host star, is an F-type star of magnitude 11.2, 310 parsecs from Earth. [40], Kappa Boötis is another wide double star. The mountain was named for the son of Lycaon, Maenalus. [13] The secondary and tertiary stars are separated by 2 arcseconds; the primary and secondary are separated by 109.1 arcseconds at an angle of 171 degrees.[39]. The primary appears to be of magnitude 4.3 and is blue-white. The brightest star in the constellation is Arcturus, Alpha Boötis, which is also the third brightest star in the night sky. [10] After Hevelius introduced Mons Maenalus in 1681, Boötes was often depicted standing on the Peloponnese mountain. Many fireballs, green-hued trails, and even some meteors that cast shadows were observed throughout the outburst, which had a maximum zenithal hourly rate of 200–300 meteors per hour. The other four dim stars are magnitude 4.91 6 Boötis, class K4; magnitude 4.86 20 Boötis, class K3; magnitude 4.81 Omega Boötis, class K4; and magnitude 4.83 A Boötis, class K1. They, however, enjoyed it a bit too much and, when they woke up the next day with bad hangovers, they assumed Icarius had tried to poison them. The Boötes void, also known as the Great Void or the Supervoid, is a sphere-shaped region of the sky, almost 250 million light years in diameter, which contains very few galaxies.
