What is Biham

Biham shines in Pegasus, the winged horse born from the blood of Medusa. Its name, from the Arabic «sa'd al-bahaim», recalls «the luck of the two beasts», a medieval asterism to which this star once belonged. A white A-class star 92 light years away, its light departed when Mozart was a child astonishing European courts at the harpsichord.
