Alpha Cancri (α Cnc, α Cancri) is a star system in the constellation Cancer. It has the traditional name Acubens (Açubens), from the Arabic , "the claws" 〔(Richard Hinckley Allen: Star Names — Their Lore and Meaning: Cancer )〕 == Properties ==
Acubens is a fourth-magnitude star with an apparent magnitude of 4.20, making it barely visible to the naked eye under good lighting conditions. Nevertheless, it is 23 times more luminous than the Sun. Its stellar classification is A5m. The Hipparcos mission estimated the distance of Acubens to be roughly 53 parsecs〔 from Earth, or approximately 174 light years away. Since it is near the ecliptic, it can be occulted by the Moon and very rarely by planets.
