Epsilon Lupi
Hot blue starWhat is Epsilon Lupi
Epsilon Lupi is a hot blue star of type B set in the body of the Wolf, about 512 light-years away. It belongs to the Scorpius–Centaurus association, the nearest gathering of young massive stars to the Sun, all born only a few million years ago from the same parent cloud. Its deep indigo colour is the signature of a surface above twenty thousand degrees —destined to a brief, brilliant life.
