Variable starWhat is Gomeisa
Gomeisa is a faintly variable blue star shining in Canis Minor, forever close to the dazzling Procyon. Its name comes from the Arabic «al-ġumayṣāʾ», meaning «the watery-eyed one», and it is drawn from a pre-Islamic legend of two stellar sisters parted forever by the great river of the Milky Way. At 162 light-years, it is relatively near — a discreet neighbour perpetually overshadowed by its more famous companion.
