Mimosa (star) - Wikipedia
The primary, β Crucis A, is a massive star with about 16 times the Sun's mass. The projected rotational velocity of this star is about 35 km s−1. However, the orbital plane of the pair is only about 10°, which probably means the inclination of the star's pole is also likely to be low.

To the eye, Mimosa would appear 2000 times brighter than the Sun; if all the radiation is taken into account, the luminosity climbs nearly 10 times higher to 19,600 solar. From these figures we calculate a radius of 6.6 times that of the Sun, in excellent agreement with the value of 7.1 solar found from the small angular radius.
