Stars named after people

Last updated

Over the past few centuries, a small number of stars have been named after individual people. It is common in astronomy for objects to be given names, in accordance with accepted astronomical naming conventions. Most stars have not been given proper names, relying instead on alphanumeric designations in star catalogues. However, a few hundred had either long-standing traditional names (usually from the Arabic) or historic names from frequent usage.

Contents

In addition, many stars have catalogue designations that contain the name of their compiler or discoverer. This includes Gliese, Wolf, Ross, Bradley, Piazzi, Lacaille, Struve, Groombridge, Lalande, Krueger, Mayer, Weisse, Gould, Luyten and others. For example, Wolf 359 was discovered and catalogued by Max Wolf.

Various private organizations claim to name stars in honor of people in exchange for a fee, but these names are used only within their own publications, and are not recognized by the scientific community.

Names approved by the IAU

The International Astronomical Union (IAU) is widely recognized by scientists and governments as the world authority for names of astronomical bodies, and lays down strict standards for this naming.

In July 2014 the IAU launched NameExoWorlds, a process for giving proper names to exoplanets and their host stars, [1] the outcome of which was announced in December 2015. [2] As a result, the IAU approved two star names after individuals: [3]

In 2016, the IAU organized a Working Group on Star Names (WGSN) [4] which will catalog cultural and historical names for bright stars to help preserve astronomical world heritage, and maintain a catalog of IAU-approved unique proper names for stars. The WGSN's first bulletin of July 2016 [5] set out its terms of reference and naming guidelines. All approved names are included on the current List of IAU-approved Star Names, last updated on 1 June 2018. [6] The WGSN rules generally discouraged the naming of stars after people, but confirmed the names Cervantes and Copernicus as well as four others:

In 2019, the IAU held a second NameExoWorlds campaign to celebrate the 100th anniversary of the IAU's founding.

Names not approved by the IAU

Apart from the few formally approved by the IAU, and leaving aside commercial attempts, stars named after individuals fall broadly into two groups. The first group are those named openly for an individual connected with them in some way. The second, somewhat more obscurely, are those named after an individual but without explicitly making this clear.

Openly named stars

There is a growing number of stars whose common names honour individuals. Many of these were highly significant in some way when discovered, usually through having some unusual characteristic. The best source to get these names is Sky Catalogue 2000.0, Volume 2 (Double Stars, Variable Stars, and Nonstellar Objects), in the chapter Glossary Of Selected Astronomical Names.

(Note that Pandora's Star and Ratner's Star are the names of novels, not actual stars.)

Covertly named stars

Some stars were given names that were disguised names of individuals, which names subsequently appeared in star catalogues and thus into more general usage.

The earliest noted example was Sualocin and Rotanev, which names have now been approved by the IAU WGSN (see above). More recently, during the Apollo program, it was common for astronauts to be trained in celestial navigation, and to use a list of naked-eye stars which to take bearings. As a practical joke, Gus Grissom gave names to three stars on this list, which were references to the three Apollo 1 crew:

The names stuck, perhaps in memoriam for their deaths in the Apollo 1 fire, and were used through the rest of the program. Unknown to Grissom, these stars already had traditional names; however, those were not generally used, allowing the three new names to make their way into other records. Today, they are generally considered disused—some sources listing them as "traditional".

It is possible, though unlikely, that further traditional names are in fact hidden names such as these, not yet identified; etymologies for many star names are not currently known.

Commercial naming

As early as 1979, when the International Star Registry was formed, private companies have attempted to sell the right to unofficially name stars. [71] These companies have no legal standing to assign any star a name, and as such these names are never recognized by the astronomical or scientific communities. The IAU does not recognize this practice, and on its website describes it as "charlatanry". [72]

<span class="mw-page-title-main">Antlia</span> Constellation in the Southern Celestial Hemisphere

Antlia is a constellation in the Southern Celestial Hemisphere. Its name means "pump" in Latin and Greek; it represents an air pump. Originally Antlia Pneumatica, the constellation was established by Nicolas-Louis de Lacaille in the 18th century. Its non-specific (single-word) name, already in limited use, was preferred by John Herschel then welcomed by the astronomic community which officially accepted this. North of stars forming some of the sails of the ship Argo Navis, Antlia is completely visible from latitudes south of 49 degrees north.

<span class="mw-page-title-main">Microscopium</span> Minor constellation in the southern celestial hemisphere

Microscopium is a minor constellation in the southern celestial hemisphere, one of twelve created in the 18th century by French astronomer Nicolas-Louis de Lacaille and one of several depicting scientific instruments.

<span class="mw-page-title-main">Piscis Austrinus</span> Constellation in the southern celestial hemisphere

Piscis Austrinus is a constellation in the southern celestial hemisphere. The name is Latin for "the southern fish", in contrast with the larger constellation Pisces, which represents a pair of fish. Before the 20th century, it was also known as Piscis Notius. Piscis Austrinus was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations. The stars of the modern constellation Grus once formed the "tail" of Piscis Austrinus. In 1597, Petrus Plancius carved out a separate constellation and named it after the crane.

<span class="mw-page-title-main">Serpens</span> Constellation split into two non-contiguous parts

Serpens is a constellation in the northern celestial hemisphere. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations designated by the International Astronomical Union. It is unique among the modern constellations in being split into two non-contiguous parts, Serpens Caput to the west and Serpens Cauda to the east. Between these two halves lies the constellation of Ophiuchus, the "Serpent-Bearer". In figurative representations, the body of the serpent is represented as passing behind Ophiuchus between Mu Serpentis in Serpens Caput and Nu Serpentis in Serpens Cauda.

<span class="mw-page-title-main">Telescopium</span> Constellation in the southern celestial hemisphere

Telescopium is a minor constellation in the southern celestial hemisphere, one of twelve named in the 18th century by French astronomer Nicolas-Louis de Lacaille and one of several depicting scientific instruments. Its name is a Latinized form of the Greek word for telescope. Telescopium was later much reduced in size by Francis Baily and Benjamin Gould.

<span class="mw-page-title-main">Vela (constellation)</span> Constellation in the southern celestial hemisphere

Vela is a constellation in the southern sky, which contains the Vela Supercluster. Its name is Latin for the sails of a ship, and it was originally part of a larger constellation, the ship Argo Navis, which was later divided into three parts, the others being Carina and Puppis. With an apparent magnitude of 1.8, its brightest star is the hot blue multiple star Gamma Velorum, one component of which is the closest and brightest Wolf-Rayet star in the sky. Delta and Kappa Velorum, together with Epsilon and Iota Carinae, form the asterism known as the False Cross. 1.95-magnitude Delta is actually a triple or quintuple star system.

<span class="mw-page-title-main">Coma Berenices</span> Constellation in the northern hemisphere

Coma Berenices is an ancient asterism in the northern sky, which has been defined as one of the 88 modern constellations. It is in the direction of the fourth galactic quadrant, between Leo and Boötes, and it is visible in both hemispheres. Its name means "Berenice's Hair" in Latin and refers to Queen Berenice II of Egypt, who sacrificed her long hair as a votive offering. It was introduced to Western astronomy during the third century BC by Conon of Samos and was further corroborated as a constellation by Gerardus Mercator and Tycho Brahe. It is the only modern constellation named for a historic person.

<span class="mw-page-title-main">Lynx (constellation)</span> Constellation in the northern celestial hemisphere

Lynx is a constellation named after the animal, usually observed in the Northern Celestial Hemisphere. The constellation was introduced in the late 17th century by Johannes Hevelius. It is a faint constellation, with its brightest stars forming a zigzag line. The orange giant Alpha Lyncis is the brightest star in the constellation, and the semiregular variable star Y Lyncis is a target for amateur astronomers. Six star systems have been found to contain planets. Those of 6 Lyncis and HD 75898 were discovered by the Doppler method; those of XO-2, XO-4, XO-5 and WASP-13 were observed as they passed in front of the host star.

<span class="mw-page-title-main">Cassiopeia (constellation)</span> Constellation in the northern celestial hemisphere

Cassiopeia is a constellation and asterism in the northern sky named after the vain queen Cassiopeia, mother of Andromeda, in Greek mythology, who boasted about her unrivaled beauty. Cassiopeia was one of the 48 constellations listed by the 2nd-century Greek astronomer Ptolemy, and it remains one of the 88 modern constellations today. It is easily recognizable due to its distinctive 'W' shape, formed by five bright stars.

<span class="mw-page-title-main">Perseus (constellation)</span> Constellation in the northern celestial hemisphere

Perseus is a constellation in the northern sky, named after the Greek mythological hero Perseus. It is one of the 48 ancient constellations listed by the 2nd-century astronomer Ptolemy, and among the 88 modern constellations defined by the International Astronomical Union (IAU). It is located near several other constellations named after ancient Greek legends surrounding Perseus, including Andromeda to the west and Cassiopeia to the north. Perseus is also bordered by Aries and Taurus to the south, Auriga to the east, Camelopardalis to the north, and Triangulum to the west. Some star atlases during the early 19th century also depicted Perseus holding the disembodied head of Medusa, whose asterism was named together as Perseus et Caput Medusae; however, this never came into popular usage.

<span class="mw-page-title-main">Circinus</span> Constellation in the southern celestial hemisphere

Circinus is a small, faint constellation in the southern sky, first defined in 1756 by the French astronomer Nicolas-Louis de Lacaille. Its name is Latin for compass, referring to the drafting tool used for drawing circles. Its brightest star is Alpha Circini, with an apparent magnitude of 3.19. Slightly variable, it is the brightest rapidly oscillating Ap star in the night sky. AX Circini is a Cepheid variable visible with the unaided eye, and BX Circini is a faint star thought to have been formed from the merger of two white dwarfs. Two sun-like stars have planetary systems: HD 134060 has two small planets, and HD 129445 has a Jupiter-like planet. Supernova SN 185 appeared in Circinus in 185 AD and was recorded by Chinese observers. Two novae have been observed more recently, in the 20th century.

<span class="mw-page-title-main">Reticulum</span> Constellation in the southern celestial hemisphere

Reticulum is a small, faint constellation in the southern sky. 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. 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.

<span class="mw-page-title-main">Leo Minor</span> Constellation in the northern celestial hemisphere

Leo Minor is a small and faint constellation in the northern celestial hemisphere. Its name is Latin for "the smaller lion", in contrast to Leo, the larger lion. It lies between the larger and more recognizable Ursa Major to the north and Leo to the south. Leo Minor was not regarded as a separate constellation by classical astronomers; it was designated by Johannes Hevelius in 1687.

<span class="mw-page-title-main">Corvus (constellation)</span> Constellation in the Southern Celestial Hemisphere

Corvus is a small constellation in the Southern Celestial Hemisphere. Its name means "crow" in Latin. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it depicts a raven, a bird associated with stories about the god Apollo, perched on the back of Hydra the water snake. The four brightest stars, Gamma, Delta, Epsilon, and Beta Corvi, form a distinctive quadrilateral or cross-shape in the night sky.

<span class="mw-page-title-main">Messier 84</span> Galaxy in the constellation Virgo

Messier 84 or M84, also known as NGC 4374, is a giant elliptical or lenticular galaxy in the constellation Virgo. Charles Messier discovered the object in 1781 in a systematic search for "nebulous objects" in the night sky. It is the 84th object in the Messier Catalogue and in the heavily populated core of the Virgo Cluster of galaxies, part of the local supercluster.

Gliese 65, also known as Luyten 726-8, is a binary star system that is one of Earth's nearest neighbors, at about 8.7 light years from Earth in the constellation Cetus. The two component stars are both flare stars with the variable star designations BL Ceti and UV Ceti.
