excerpt

MIMOSA (Beta Crucis). Few are the first magnitude stars, as their apparent brightness requires either great luminosity, closeness, or both. Mimosa satisfies the first requirement.

And ther came a voyce from heaven: Thou arte my dere sonne in whom I delyte. Mark 1:11 TYN

The origin of its name, which comes from Latin and means “actor,” is not clear, but may derive from that of the beautiful southern-hemisphere flower.
A rotation velocity of at least 40 kilometers per second gives a rotation period under 8 days.
Mimosa itself is clearly above the cutoff of 8 to 10 solar masses, beyond which stars explode as supernovae. It has perhaps only six or so million years left to go.
