Phi 2 Lupi
Hot blue starWhat is Phi 2 Lupi
Phi-2 Lupi is a hot blue B-type star in the body of the Wolf, a southern constellation rich in young suns tied to the great Scorpius-Centaurus association. About 519 light-years away, it drifts through the galaxy in the same neighbourhood as many spectral siblings of common origin, forming one of the largest associations of young stars near the Solar System. Its crisp blue light, carried across centuries to reach us, is a small fragment of the collective breath of that stellar cradle spread across the southern sky.
