In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
A primary star, which is brighter and typically bigger than its companion stars, is designated by a capitalized A. Its companions are labelled B, C, and so on. For example, Sirius, the brightest star in the sky, is actually a double star, consisting of the naked-eye visible Sirius A and its dim white-dwarf companion Sirius B.
The star Chi Virginis has one of the most massive planets ever detected, with a mass of 11.1 times that of Jupiter. The sun-like star 61 Virginis has three known planets: one is a super-Earth and two are Neptune-mass planets. SS Virginis is a variable star with a noticeable red color. It varies in magnitude from a minimum of 9.6 to a maximum of ...
T Coronae Borealis (T CrB), nicknamed the Blaze Star, is a binary star and a recurrent nova about 3,000 light-years away in the constellation Corona Borealis. [11] It was first discovered in outburst in 1866 by John Birmingham, [12] though it had been observed earlier as a 10th magnitude star. [13] It may have been observed in 1217 and in 1787 ...
ζ Gem (Mekbuda) is a double star, whose primary is a Cepheid variable star with a period of 10.2 days; its minimum magnitude is 4.2 and its maximum magnitude is 3.6. It is a yellow supergiant, 1,200 light-years from Earth, with a radius that is 60 times solar, making it approximately 220,000 times the size of the Sun .
The Bright Star Catalogue, which is a star catalogue listing all stars of apparent magnitude 6.5 or brighter, or roughly every star visible to the naked eye from Earth, contains 9,096 stars. [1] The most voluminous modern catalogues list on the order of a billion stars, out of an estimated total of 200 to 400 billion in the Milky Way .
First published in 1899 as Star-Names and Their Meanings, [2] this work collected the origins of the names of stars and constellations from a panoply of sources, some primary but most secondary; also telling briefly the various myths and folklore connected with stars in the Greco-Roman tradition; as well as in the Arabic, Babylonian, Indian and Chinese traditions, for which, however, some ...
Located 131±1 light-years from Earth, [9] it is an orange-hued giant star that has swollen and cooled off the main sequence to become an orange giant with a radius 11 times and luminosity 53 times that of the Sun. [11] Its common name means "southern donkey". [1] The star also holds a record for the longest name, "Arkushanangarushashutu ...
