(19.8 ± 0.3 pc)Spectral type K1III Other designations Nu² Canis Majoris (ν² CMa, ν² Canis Majoris) is a star in the constellation Canis Major.
ν² Canis Majoris is an orange K-type giant with an apparent magnitude of +3.95. It is approximately 64.7 light years from Earth. It is orbitted by a gas giant planet at 1.9AU.[1]
Chinese name
In Chinese astronomy, ν² Canis Majoris is called 野雞, Pinyin: Yějī, meaning Wild Cockerel, because this star is marking itself and stand alone in Wild Cockerel asterism, Well mansion (see : Chinese constellation)[2]. 野雞 (Yějī), westernized into Ya Ke. According to R.H. Allen opinion, the name Ya Ke is asterism consisting ο1 Canis Majoris and π Canis Majoris, with other small stars in the body of the Dog[3]
