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.
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.
Canis Major is a constellation in the southern celestial hemisphere.

The Catalogue of Fundamental Stars is a series of six astrometric catalogues of high precision positional data for a small selection of stars to define a celestial reference frame, which is a standard coordinate system for measuring positions of stars.
Astronomy in China has a very long history, with historians indicating that the Chinese were the most persistent and accurate observers of celestial phenomena anywhere in the world before the Arabs.
Traditional Chinese astronomy has a system of dividing the celestial sphere into asterisms or constellations, known as "officials" (Chinese xīng guān).
In modern astronomy, a constellation is a specific area of the celestial sphere as defined by the International Astronomical Union (IAU).

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.

In astronomy, an epoch is a moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or elliptical orbital elements of a celestial body, because these are subject to perturbations and vary with time.
A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature.

The Gliese Catalogue of Nearby Stars is a modern star catalogue of stars located within 25 parsecs (81.54 ly) of the Earth.
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.

The Bayer designation Nu Canis Majoris (ν CMa / ν Canis Majoris) is shared by three star systems, in the constellation Canis Major.
Nu2 Canis Majoris b, (7 CMa b) is a water cloud jovian extrasolar planet orbiting the star Nu2 Canis Majoris, approximately 64.71lys away in the constellation of Canis Major.
Omicron1 Canis Majoris (ο1 CMa, ο1 Canis Majoris) is a star in the constellation Canis Major.
Pi Canis Majoris (π CMa, π Canis Majoris), also known as 19 Canis Majoris, is a star in the constellation Canis Major located approximately 96 light years from Earth.
Pinyin, or Hanyu Pinyin, is the official phonetic system for transcribing the Mandarin pronunciations of Chinese characters into the Latin alphabet in China, Taiwan, and Singapore. It is often used to teach Standard Chinese and a pinyin without diacritic markers is often used in foreign publications to spell Chinese names familiar to non-Chinese and may be used as an input method to enter Chinese characters into computers. The Hanyu Pinyin system was developed in the 1950s based on earlier forms of romanization. It was published by the Chinese government in 1958 and revised several times. The International Organization for Standardization (ISO) adopted pinyin as an international standard in 1982. The system was adopted as the official standard in Taiwan in 2009, where it is used for romanization alone rather than for educational and computer input purposes. The word Hànyǔ means the spoken language of the Han people and pīnyīn literally means "spelled-out sounds".

In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
The Astrophysical Journal, often abbreviated ApJ (pronounced "ap jay") in references and speech, is a peer-reviewed scientific journal of astrophysics, established in 1895 by American astronomers George Ellery Hale and James Edward Keeler.
The Well mansion (井宿, pinyin: Jǐng Xiù; Japanese: chichiri-boshi) is one of the Twenty-eight mansions of the Chinese constellations.
