Absolute magnitude is the measure of intrinsic brightness of a celestial object.

The apparent magnitude (m) of a celestial object is a measure of its brightness as seen by an observer on Earth, adjusted to the value it would have in the absence of the atmosphere.

A Bayer designation is a stellar designation in which a specific star is identified by a Greek letter, followed by the genitive form of its parent constellation's Latin name.

Boss General Catalogue (GC, sometimes General Catalogue) is an astronomical catalogue containing 33,342 stars.
The Bright Star Catalogue, also known as the Yale Catalogue of Bright Stars or Yale Bright Star Catalogue, 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.

The Cape Photographic Catalogue (CPC) is a star catalog containing 68,467 stars in the Southern Hemisphere whose declinations are either between −30° and −40° or between −52° and −90°.
Centaurus is a bright constellation in the southern sky.

In astronomy, Durchmusterung or Bonner Durchmusterung (BD), is the comprehensive astrometric star catalogue of the whole sky, compiled by the Bonn Observatory (Germany) from 1859 to 1903.

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.
Hipparcos was a scientific satellite of the European Space Agency (ESA), launched in 1989 and operated until 1993.

A light-year (abbreviation: ly), sometimes written light year, is a unit of length used informally to express astronomical distances.

A parsec (symbol: pc) is a unit of length used to measure the astronomically large distances to objects outside the Solar System.

The Smithsonian Astrophysical Observatory Star Catalog is an astrometric star catalogue.
The solar mass is a standard unit of mass in astronomy that is used to indicate the masses of other stars, as well as clusters, nebulae and galaxies.

A star is a luminous sphere of plasma held together by its own gravity.

A star system or stellar system is a small number of stars that orbit each other, bound by gravitational attraction.

In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates.
New!!: H Centauri and Variable star ·
Variable stars are designated using a variation on the Bayer designation format of an identifying label (as described below) combined with the Latin genitive of the name of the constellation in which the star lies.
