Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See Q Centauri and Apparent magnitude
Binary star
A binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other. Q Centauri and binary star are binary stars.
See Q Centauri and Binary star
Bright Star Catalogue
The Bright Star Catalogue, also known as the Yale Catalogue of Bright Stars, Yale Bright Star Catalogue, or just YBS, is a star catalogue that lists all stars of stellar magnitude 6.5 or brighter, which is roughly every star visible to the naked eye from Earth. Q Centauri and bright Star Catalogue are bright Star Catalogue objects.
See Q Centauri and Bright Star Catalogue
Centaurus
Centaurus is a bright constellation in the southern sky.
Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object.
See Q Centauri and Constellation
Durchmusterung
In astronomy, Durchmusterung or Bonner Durchmusterung (BD) is an astrometric star catalogue of the whole sky, published by the Bonn Observatory in Germany from 1859 to 1863, with an extension published in Bonn in 1886.
See Q Centauri and Durchmusterung
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life.
Henry Draper Catalogue
The Henry Draper Catalogue (HD) is an astronomical star catalogue published between 1918 and 1924, giving spectroscopic classifications for 225,300 stars; it was later expanded by the Henry Draper Extension (HDE), published between 1925 and 1936, which gave classifications for 46,850 more stars, and by the Henry Draper Extension Charts (HDEC), published from 1937 to 1949 in the form of charts, which gave classifications for 86,933 more stars. Q Centauri and Henry Draper Catalogue are Henry Draper Catalogue objects.

Hipparcos
Hipparcos was a scientific satellite of the European Space Agency (ESA), launched in 1989 and operated until 1993.
Light-year
A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi.
Main sequence
In astronomy, the main sequence is a classification of stars which appear on plots of stellar color versus brightness as a continuous and distinctive band.
See Q Centauri and Main sequence
Minute and second of arc
A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol, is a unit of angular measurement equal to of one degree.
See Q Centauri and Minute and second of arc
Smithsonian Astrophysical Observatory Star Catalog
The Smithsonian Astrophysical Observatory Star Catalog is an astrometric star catalogue, created by Smithsonian Institution, a research institute.
See Q Centauri and Smithsonian Astrophysical Observatory Star Catalog
Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
