About Grus (constellation) in brief
Grus is a constellation in the southern sky. Its name is Latin for the crane, a type of bird. It is one of twelve constellations conceived by Petrus Plancius from observations of Pieter Dirkszoon Keyser and Frederick de Houtman. Grus, Pavo, Phoenix and Tucana are collectively known as the “Southern Birds”. The constellation’s brightest star, Alpha Gruis, is also known as Alnair and appears as a 1. 7-magnitude blue-white star. The stars that form Grus were originally considered part of the neighbouring constellation Piscis Austrinus, with Gamma Gruis seen as part of a fish’s tail. Six star systems have been found to have planets: the red dwarf Gliese 832 is. one of the closest stars to Earth to have a planetary system. Another—WASP-95—has a planet that orbits every two days. The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined as a polygon of 6 segments of 6 square degrees. In the equatorial coordinate system, the borders lie between 21h 27m and 23h 1m 1m, while the declination coordinates are between 31° 31m and 39° 39° 1m. The three-letter abbreviation for the constellation, adopted by the International Astronomical Union in 1922, is “Gru” Grus is located between 31h 27h and 4m 1 m, while declination is 31h 31m 0m, while the latitude is 21h 31h 0m and the longitude is 23h 4m 0 m.
It ranks 45th in size and covers 45th straight square degrees, 0.87% of the night sky and covers 887 square degrees of the sky. It was depicted in Johann Bayer’s star atlas Uranometria of 1603. French explorer and astronomer Nicolas-Louis de Lacaille gave Bayer designations to its stars in 1756, some of which had been previously considered part. Some of the stars in Grus are known as Grus stars. The constellation is bordered by Piscis Austrinus to the north, Sculptor to the northeast, Phoenix to the east, Tucana to the south, Indus to the southwest, and Microscopium to the west. In Central Australia, the Arrernte and Luritja people living on a mission in Hermannsburg viewed the sky as divided between them, east of the Milky Way representing ArrerNTe camps and west denoting Luritaja camps. Alpha and Beta Gruis along with Fomalhaut, Alpha Pavonis and the stars of Musca, were all claimed by the Arrersnte. The star system of Grus was first seen in 1598 in Amsterdam by Plancius and Jodocus Hondius.
