Alamak

Almach, Almaak, Gamma1 Andromedae, 57 Andromedae

In the east of Andromeda, towards the hero Perseus, is one of the sky's most famous multiple systems. Two close bright stars, one blue and one yellow, are presently converging on each other. They met in 2012, and are now separating again. Meanwhile, a third component circles these two along a decades-long orbit.
