About Canis Major in brief

Among the Merazig of Tunisia, shepherds note six constellation that mark the passage of the dry, hot season. One of these includes Canis Minor, which is the sign of the end of the summer. The red hypergiant VY Canis majoris is one of the largest stars known. The neutron star RX J0720. 4-3125 has a radius of a mere 5 km. It is also believed that the constellation contains the stars Omicron2, Beta or Nu2, Nu1, Nu2 and Nu3, although it is uncertain which stars were depicted in the Chinese asterism of the Wild Cockerelus, although some have suggested Nu1 and Pi might have been them, while Nu2 or Beta2 may have been Nu1 or Nu3. The constellation is also known as Canis minor, which means ‘the lesser dog’ or ‘the smaller dog’ in Latin. The Milky Way passes through the constellation, and several open clusters lie within its borders, most notably M41. In contrast, the other bright stars in the constellation are stars of great distance and high luminosity. At magnitude 1. 5, Epsilon CanisMajoris is the second-brightest star of the constellation and the brightest source of extreme ultraviolet radiation in the evening sky. The ancient Greeks replaced the bow and arrow depiction with that of a dog, and referred to the dog Laelaps.
