In astronomy, stars have a variety of different stellar designations and names, including catalogue designations, current and historical proper names, and foreign language names. Only a tiny minority of known stars have proper names ; all others have only designations from various catalogues or lists, or no identifier at all.
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 ...
Near-Earth objects (such as 1862 Apollo) receive mythological names, except those associated with creation or the underworld, while distant Amor asteroid (with perihelion larger than 1.15 au) may receive non-mythical names. Jupiter trojans (objects in a 1:1 orbital resonance with Jupiter) are named for characters of the legendary Trojan War.
A type of binary system where evidence for an unseen orbiting companion is revealed by its periodic gravitational perturbation of the visible component. See also spectroscopic binary. astrometry The branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies. astronomical body
Its name is Latin for a small net, or reticle—a net of crosshairs at the focus of a telescope eyepiece that is used to measure star positions. [2] The constellation is best viewed between October and December, and save for one main star visible in ideal conditions, cannot be seen from north of the 30th parallel north. [3]
Feigelson (for example: open star cluster Feigelson 1 at 11:59:51 / -78°12'27", in Chamaeleon, at the binary star Epsilon Chamaeleonis) Ferrero (telescopic asterisms) Φ — W.S. Finsen (double stars)
A child's right to a private life was intruded upon when a judge refused them permission to change their name to a non-binary one they wished to use, appeal judges found.
The most common kinds of binary system are binary stars and binary asteroids, but brown dwarfs, planets, neutron stars, black holes and galaxies can also form binaries. A multiple system is similar but consists of three or more objects, for example trinary stars and trinary asteroids .
