Beta and Crucis
The four main stars that form the asterism are Alpha, Beta, Gamma, and Delta Crucis.
Beta Crucis, called Mimosa, is a blue-hued giant of magnitude 1. 3, 353 light-years from Earth.
The southern celestial pole lies at the intersection of ( a ) the line along the long axis of crux ( i. e. through Alpha Crucis and Gamma Crucis ) and ( b ) a line perpendicularly bisecting the line joining the " Pointers " ( Alpha Centauri and Beta Centauri ).
Beta Crucis, also known as Mimosa or Becrux, is the second brightest star in the constellation Crux ( after Alpha Crucis or Acrux ) and is the 19th brightest star in the night sky.
Although Beta Crucis, " Becrux ", is at roughly − 60 ° declination, and therefore not visible north of 30 °, in the time of the ancient Greeks and Romans it was visible north of 40 ° due to the precession of equinoxes, and these civilizations regarded it as part of the constellation Centaurus.
Beta Crucis is believed to be the hottest first-magnitude star, with an apparent visual magnitude of 1. 25.
The primary, Beta Crucis A, is a massive star with about 16 times the Sun's mass.
Beta Crucis A is a known Beta Cephei variable, although with an effective temperature of about 27, 000 K it is at the high end of the instability strip where such stars are found.
The Beta Crucis system may be a member of the Lower Centaurus-Crux sub-group of the Scorpius-Centaurus Association.

Thus Beta Crucis appears to the right of the constellation and Delta Crucis to the left, in mirror image of the way they actually appear in the sky ( and, coincidentally, the way they appear on the Brazilian coat of arms ).
The cluster looks like a star to the unaided eye and appears close to the easternmost star of the Southern Cross, ( Beta Crucis ), so is only visible from southern latitudes.
The Jewel Box cluster can be easily located using the star Beta Crucis as a guide, and appears as a fourth magnitude object.
Delta Crucis is a strong candidate Beta Cephei variable and changes its brightness subtly with a period of 1. 3 hours.
