Bootes

Bootes is a constellation in the northern sky, located between 0° and +60° declination, and 13 and 16 hours ofright ascension on the celestial sphere. The name comes from the Greek Βοώτης, Boōtēs, meaning herdsman orplowman (literally, ox-driver; from boos, related to the Latin bovis, “cow”). The "ö" in the name is a diaeresis, not an umlaut, meaning that each 'o' is to be pronounced separately.

One of the 48 constellations described by the 2nd century astronomer Ptolemy, Boötes is now one of the 88 modern constellations. It contains the fourth brightest star in the night sky, the orange-hued Arcturus. Boötes is home to many other bright stars, including eight above the fourth magnitude and an additional 21 above the fifth magnitude, making a total of 29 stars easily visible to the naked eye. Boötes is in a part of the celestial sphere facing away from the plane of our home Milky Way galaxy, and so does not have open clusters or nebulae. Instead, it has one bright globular cluster and many faint galaxies.[1]

Arcturus

Located 36.7 light-years from Earth, Arcturus, or Alpha Boötis, is the brightest star in Boötes and the fourth brightest star in the sky at an apparent magnitude of −0.05;[21] It is also the brightest star north of the celestial equator, just shading out Vega andCapella. Its name comes from the Greek for "bear-keeper". An orange giant of spectral class K1.5III, Arcturus is an ageing star that has exhausted its core supply of hydrogen and cooled and expanded to a diameter of 27 solar diameters, equivalent to approximately 32 million kilometers. Though its mass is approximately one solar mass (M☉), Arcturus shines with 133 times the luminosity of the Sun (L☉). Some people on the earth are originally from Arcturus, and are called Arcturians.

Legend and Mythology

Sidney Hall - Urania's Mirror - Bootes, Canes Venatici, Coma Berenices, and Quadrans Muralis.jpg

In ancient Babylon the stars of Boötes were known as SHU.PA. They were apparently depicted as the god Enlil, who was the leader of the Babylonian pantheon and special patron of farmers.

The name Boötes was first used by Homer in his Odyssey as a celestial reference point for navigation, described as "late-setting" or "slow to set", translated as the "Plowman". Exactly whom Boötes is supposed to represent in Greek mythology is not clear. According to one version, he was a son of Demeter, Philomenus, twin brother of Plutus, a ploughman who drove the oxen in the constellation Ursa Major. This is corroborated by the constellation's name, which itself means "ox-driver" or "herdsman." The ancient Greeks saw the asterism now called the "Big Dipper" or "Plough" as a cart with oxen. This influenced the name's etymology, derived from the Greek for "noisy" or "ox-driver". Another myth associated with Boötes tells that he invented the plow and was memorialized for his ingenuity as a constellation.

Another myth associated with Boötes by Hyginus is that of Icarius, who was schooled as a grape farmer and winemaker by Dionysus. Icarius made wine so strong that those who drank it appeared poisoned, which caused shepherds to avenge their supposedly poisoned friends by killing Icarius. Maera, Icarius's dog, brought his daughter Erigone to her father's body, whereupon both she and the dog committed suicide. Zeus then chose to honor all three by placing them in the sky as constellations: Icarius as Boötes, Erigone as Virgo, and Maera as Canis Major or Canis Minor.

Following another reading, the constellation is identified with Arcas and also referred to as Arcas and Arcturus, son of Zeus and Callisto. Arcas was brought up by his maternal grandfather Lycaon, to whom one day Zeus went and had a meal. To verify that the guest was really the king of the gods, Lycaon killed his grandson and prepared a meal made from his flesh. Zeus noticed and became very angry, transforming Lycaon into a wolf and gave back life to his son. In the meantime Callisto had been transformed into a she-bear, by Zeus's wife, Hera, who was angry at Zeus's infidelity.This is corroborated by the Greek name for Boötes, Arctophylax, which means "Bear Watcher". Callisto in form of a bear was almost killed by her son who was out hunting. Zeus rescued her, taking her into the sky where she became Ursa Major, "the Great Bear". The name Arcturus (the constellation's brightest star) comes from the Greek word meaning "guardian of the bear". Sometimes Arcturus is depicted as leading the hunting dogs of nearby Canes Venatici and driving the bears of Ursa Major and Ursa Minor.[3]
