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.
Mimosa is a hot, blue B0.5III giant having a luminosity about 3200 times that of the sun and a diameter about 8 times that of the sun.

Beta Crucis (Mimosa) is the brightest star of the group, a blue-white giant (nearly five times the Sun's size) with a visual magnitude of 1.25. The star is an estimated 580 light years away, and has a luminosity of nearly 8000.
Also on board was a small spark chamber experiment called MIMOSA for observations of gamma-rays from 70-300 MeV. The instrument was equipped with a stereoscopic TV system viewing through the chamber portholes to record the particle tracks.
a) Canopus is brighter than Mimosa as it has a lower value for apparent magnitude (-0.62
b) With only apparent magnitude information provided it is impossible to state which of the two stars is intrinsically more luminous.
Other fanzines to win awards in recent years include File 770, Mimosa, and Plokta.[85] Artists working for fanzines have risen to prominence in the field, including Brad W.
[3019] beta Crucis, also known as Mimosa (because of its colour) or Becrux, is the brightest star in Crux and also among the brightest stars in the sky. It is a blue-white giant visible only south of the Tropic of Cancer.

The second-brightest star is Becrux or Mimosa (Beta Cru); the third-brightest is Gacrux (Gamma Cru). The Jewel Box (also known as Kappa Crucis) is an open cluster of about 100 stars in the Southern Cross.
The star lies in the part (12:31:10.0-57:6:47.6, ICRS 2000.0) or "top" of Constellation Crux (see chart and photo), the Southern Cross -- northwest of Mimosa (Beta Crucis), northeast of Delta Crucis, and north of Acrux (Alpha Crucis).
