Aquila (Latin for Eagle; sometimes named the Vulture), is one of the 48 constellations listed by Ptolemy, also mentioned by Eudoxus (4th cent. B.C.) and Aratus (3rd cent. B.C.). and now also part of the list of 88 constellations acknowledged by the IAU. It lies roughly at the celestial equator. The alpha star, Altair, is a vertex of the so-called "Summer Triangle".
Ptolemy catalogued nineteen stars jointly in this constellation and in the constellation Antinous, which was named in the reign of the emperor H ...

Apus (Latin for bird of paradise or swallow, from Greek απους, lit. "no-feet") is a faint southern constellation, not visible to the ancient Greeks. The constellation was one of twelve constellations created by Pieter Dirkszoon Keyser and Frederick de Houtman between 1595 and 1597, and it first appeared in Johann Bayer's Uranometria of 1603.

Alpha Piscium (α Psc) is a star in the constellation Pisces. It also has the traditional name Alrischa or Alrescha (Arabic for "the rope").
The distance to α Psc is about 139 light years. The system comprises a close double star with angular separation of presently 1.8" between the components. The main star is of magnitude +4.33 and spectral type A0p, while the companion is magnitude 5.23 and belongs to spectral class A3m. The two stars take more than 700 years to orbit one another and they will make their close ...
Acrux (α Cru / α Crucis / Alpha Crucis) is the brightest star in constellation Crux (the Southern Cross) and the thirteenth brightest star in the nighttime sky, at visual magnitude 0.77.
Since Acrux is at roughly −60° declination, it is only visible south of the Tropic of Cancer and therefore didn't receive an ancient traditional name; "Acrux" is simply a combination of the A in Alpha plus Crux. Acrux is the southernmost first magnitude star, ju ...
Cthulhu (alternate spellings: Tulu, Cthulu, Ktulu, and many others) is a fictional character in the Cthulhu mythos of H.P. Lovecraft. Cthulhu often includes the title Great or Dread.
Cthulhu's name is usually pronounced /kəˈθuːluː/, /kəˈθʊːluː/, or /kəˈtʰʊːluː/ (IPA transliteration); however, according to Lovec ...

Alpha Centauri (α Cen / α Centauri) is the brightest star system (a triple star system) in the southern constellation of Centaurus, and contains the fourth brightest star in the night sky, with an apparent visual magnitude of −0.01. It is famous in the Southern Hemisphere as the outermost “pointer” to the Southern Cross, but it is too far south to be visible in most of the northern hemisphere. To the naked eye, the two brightest components of the system are too close for the eye to ...
In astronomy, many stars are referred to simply by catalogue numbers. There are a great many different star catalogues which have been produced for different purposes over the years, and this article covers only some of the more frequently quoted ones. Most of the recent catalogues are available in electronic format and can be freely downloaded from NASA's Astronomical Data Center and other places (see links at end).

Vela (Latin for sails) is a southern constellation, one of the four parts into which Argo Navis was split (the others being; Carina (constellation), Puppis and Pyxis.
It contains the stars Delta Velorum and Kappa Velorum which together with Iota Carinae and Epsilon Carinae form the asterism known as the "false cross", which is sometimes mistaken for the Southern Cross.
Of the deep sky objects of interest in Vela is a planetary nebula known as the Eight-Burst nebula. Also of interest within the constellation is the ...
Ursa Minor is a constellation in the northern sky, the name of which means Small Bear in Latin. It is one of the 88 modern constellations, and was also one of the 48 listed by Ptolemy. It is notable as the location of the north celestial pole, although this will change after some centuries due to the precession of the equinoxes.
Ursa Minor - Notable features.
Ursa Minor contains an asterism colloquially known as the Little Dipper because its seven brightest stars seem to form a ladle, or dippe ...
Ursa Major (Ursa Maior in Latin) is a constellation visible throughout the year in the northern hemisphere. Its name means Great Bear in Latin, and is associated with the legend of Callisto.
Ursa Major - Notable features.
The seven brightest stars, located in the Bear's hindquarters and tail, form the well-known Big Dipper asterism. Except for Dubhe and Alkaid, the stars of the Big Dipper all have proper motions heading towards a common point in Sagittarius. A few other such stars have been identifie ...
A visual binary star is a binary star for which the angular separation between the two components is great enough to permit them to be observed as a double star in a telescope. The resolving power of the telescope is an important factor in the detection of visual binaries, and as telescopes become larger and more powerful an increasing number of visual binaries will be detected. The brightness of the two stars is also an important factor, as brighter stars are harder ...
Volans, being Latin for flying fish, is a constellation of the southern sky. The constellation was one of twelve constellations created by Pieter Dirkszoon Keyser and Frederick de Houtman between 1595 and 1597, and it first appeared in Johann Bayer's Uranometria of 1603.

Aquarius (Latin for the Water-bearer or Cup-bearer, symbol , Unicode ♒) is the eleventh sign of the zodiac, situated between Capricornus and Pisces. Its symbol is , representing part of a stream of water.
Aquarius is one of the oldest recognized constellations along the zodiac, the sun's apparent path. It is found in a region often called the Sea due to its profusion of watery constellations such as Cetus, Pisces, Eridanus, etc. Sometimes, the river Eridanus is depicted spilling from Aquarius' watering pot.

A binary star system consists of two stars both orbiting around their barycenter. For each star, the other is its "companion star".
The term "binary star" was apparently first coined by Sir William Herschel in 1802 to designate "a real double star — the union of two stars that are formed together in one system by the laws of attraction". Any two stars seen close to one another form a double star, the most famous being Mizar and Alcor in the Big Dipper. Odds are, though, that a double star is probably a foreground and b ...
Albireo (β Cyg / β Cygni / Beta Cygni) is the third brightest star in the constellation Cygnus. Although it has the Bayer designation "beta", it is actually fainter than Gamma Cygni.
Since Cygnus is "the swan", and Albireo is located at the head of the swan, it is sometimes called the "beak star". It also forms the "Northern Cross" along with Deneb, Delta Cygni and Eta Cygni.
The name of the star have come to originate by misunderstandings and wrong translations. The name of the star was originally al-Minhar al-Daja ...
