, The medieval Arabic astronomers maintained the depiction of Canis Minor (al-Kalb al-Asghar in Arabic) as a dog; in his Book of the Fixed Stars, Abd al-Rahman al-Sufi included a diagram of the constellation with a canine figure superimposed.  AZ is of spectral type A5IV, and ranges between magnitudes 6.44 and 6.51 over a period of 2.3 hours.  Although it has an apparent magnitude of 4.34, Gamma Canis Minoris is an orange K-type giant of spectral class K3-III C, which lies 318 light-years (97 parsecs) away. A yellow-white main sequence star, it has a white dwarf companion. Canis Major spans over 20 degrees of the Zodiac in the Sign of Cancer, and contains 11 named fixed stars. The stars of Canis Minor were incorporated along with some stars of Orion and Gemini into an asterism associated with the day called "Water".  It is then seen earlier in the evening until July, when it is only visible after sunset before setting itself, and rising in the morning sky before dawn. One of them, called Merzem, includes the stars of Canis Minor and Canis Major and is the herald of two weeks of hot weather. , A red giant of spectral type M4III, BC Canis Minoris lies around 500 light-years (150 parsecs) distant from the Solar System. including the brightest star in the night sky, Sirius the Dog Star. Covering 183 square degrees, Canis Minor ranks seventy-first of the 88 constellations in size. , The 11 Canis-Minorids, also called the Beta Canis Minorids, are a meteor shower that arise near the fifth-magnitude star 11 Canis Minoris and were discovered in 1964 by Keith Hindley, who investigated their trajectory and proposed a common origin with the comet D/1917 F1 Mellish.  The last of the trio, Delta3 (also known as 9 Canis Minoris), is a white main sequence star of spectral type A0Vnn and magnitude 5.83 which is 680 light-years (210 parsecs) distant.  These stars mark the paws of the Lesser Dog's left hind leg, while magnitude 5.13 Zeta marks the right. It is one of the brightest known ultraviolet sources in the sky. Delta1 is a yellow-white F-type giant of magnitude 5.25 located around 790 light-years (240 parsecs) from Earth.  Its colour is obvious when seen through binoculars.  Luyten's Star (GJ 273) is a red dwarf star of spectral type M3.5V and close neighbour of the Solar System. The two components of Gamma A orbit each other every 389.2 days, with an eccentric orbit that takes their separation between 2.3 and 1.4 astronomical units (AU). , The Aztec calendar was related to their cosmology. The 11 Canis-Minorids are a meteor shower that can be seen in early December. Combined with additional stars in Gemini, Shuiwei represented an official who managed floodwaters or a marker of the water level. Canis Minor was also given the name DAR.LUGAL, its position defined as "the star which stands behind it [Orion]", in the MUL.APIN; the constellation represents a rooster. It appears prominently in the southern sky during the Northern Hemisphere's winter.
mag. = absolute magnitude (Mv)  In Bayer's 1603 work Uranometria, Procyon is located on the dog's belly, and Gomeisa on its neck.  BI is of spectral type F2 with an apparent magnitude varying around 9.19 and a period of approximately 2.91 hours.  A similar situation has occurred with NGC 2394, also in Canis Minor.  Also known as 8 Canis Minoris, Delta2 is an F-type main-sequence star of spectral type F2V and magnitude 5.59 which is 136 light-years (42 parsecs) distant.  Epsilon Canis Minoris is a yellow bright giant of spectral class G6.5IIb of magnitude of 4.99. Although their skin had turned to bark, they were able to speak with a human voice by rustling their leaves.  AD has a spectral type of F2III, and has a maximum magnitude of 9.21 and minimum of 9.51, with a period of approximately 2.95 hours. 3SharesConstellation Canis Major Astrology Constellation Canis Major the Greater Dog, sits south of constellation Gemini, between constellation Orion and constellation Argo Navis.
Along with Zeta and 8 Cancri, 6 Canis Minoris and 11 Canis Minoris formed the asterism Shuiwei, which literally means "water level". , Constellation straddling the celestial equator, The 41 additional constellations added in the 16th, 17th and 18th centuries, Mark R.
