Gamma Cancri (γ Cnc, γ Cancri) is a star system in the constellation Cancer. It has the traditional name Asellus Borealis (Latin for "northern donkey colt").
In Chinese, 鬼宿 (Guǐ Su), meaning Ghost (asterism), refers to an asterism consisting of γ Cancri, θ Cancri, η Cancri and δ Cancri.[3] Consequently, γ Cancri itself is known as 鬼宿三 (Guǐ Su sān, English: the Third Star of Ghost.)[4]
Gamma Cancri is a white A-type subgiant with an apparent magnitude of +4.67. [1] Located around 181 light-years distant, it shines with a luminosity approximately 35 times that of the Sun and has a surface temperature of 9108 K.[5] Since it is near the ecliptic, it can be occulted by the Moon and, very rarely, by planets. It will die in about 510 million years.
