Alkaid (Eta Ursae Majoris)
The second brightest star in the constellation Ursa
Major and the end star in the handle of the Big
Dipper (Plough). Its name (alternatively given as "Benetnasch") is a
contraction of the phrase Ka'id Banat al Na'ash meaning "chief mourner
of the daughters of Al Na'ash"; (the latter represented by stars in the
Dipper's handle) that stand by a funeral bier made of the Dipper's bowl.
Alkaid is just below the temperature limit at which stars generate strong X-rays because of shock
waves in their winds. Unlike the other members of the Big Dipper asterism,
Alkaid does not belong to the Ursa
Major moving cluster.
|Alkaid is the most eastern star in
the Big Dipper (Plough).
