Variable star

Its story

η Orionis is one of the most studied multiple systems in the hunter's belt: a knot of several hot B-type stars that eclipse one another in a rhythm of less than eight days. The Orion stellar association, one of the most active nurseries in the Milky Way, frames her in the night. Her light has been crossing the void for nearly a millennium.
