Delta Cancri (δ Cnc, δ Cancri) is an orange giant star approximately 180 light-years away in the constellation Cancer. It has the traditional name Asellus Australis which in Latin means "southern donkey colt". It also has the longest of all known star names, Arkushanangarushashutu, derived from ancient Babylonian which means "the southeast star in the Crab".
In Chinese, 鬼宿 (Guǐ Su), meaning Ghost (asterism), refers to an asterism consisting of δ Cancri, θ Cancri, η Cancri and γ Cancri. Consequently, δ Cancri itself is known as 鬼宿四 (Guǐ Su sì, English: the Fourth Star of Ghost.)
Since it is near the ecliptic, it can be occulted by the Moon and very rarely by planets.
