Alhena
Gamma Geminorum
Names For This Star
Alhena derives from the Arabic term Al Han'ah. The Arabic term apparently means a brand or mark on the right side of the neck of a horse or camel. According to Allen, one Arab author has defined the term as "Winding", since the stars in this area of the sky appear to be winding around each other or curving outwards from the central star.
Description of the Star
Alhena is a white A0IVsubgiant about 5 times larger than the sun in diameter about 150 times as luminous.
