Mimosa, Beta Crucis (β Cru), is a multiple star system located in the constellation Crux.
β Crucis is the system's Bayer designation. The name was officially approved by the International Astronomical Union’s (IAU) Working Group on Star Names (WGSN) on July 20, 2016.The star’s other name, Becrux (pronunciation: /ˈbeɪkrʌks/, is a contraction of its Bayer designation, Beta, and the name of the constellation to which it belongs, Crux.At about -60° declination, Beta Crucis cannot be seen from locations north of latitude 30°N.To observers in southern latitudes, Beta Crucis is very easy to find because it is bright and part of the Southern Cross. The Southern Cross is easy to identify, as two exceptionally bright stars, Alpha and Mimosa can be used to find one of the brightest and finest open clusters in the sky. Beta Crucis, also called Mimosa or Becrux, second brightest star (after Alpha Crucis) in the southern constellation Crux (the Southern Cross) and the 20th brightest star in the sky. In ancient times, the stars of the Southern Cross were visible north of latitude 40°N, but have since sunk below the horizon for most northern observers due to the precession of the equinoxes. Mimosa (Beta Crucis) is a blue giant star that can be located in the constellation of Crux. Beta Crucis is a spectroscopic binary star system composed of a pair of stars that complete an orbit every 5 years (1,828 ± 2.5 days) at a separation between 5.4 and 12 astronomical units. Beta Crucis (GC5Y96N) was created by DeFCoN_6 on 6/27/2015. In ancient Greece and Rome, the stars of Crux were considered to be part of the larger constellation Centaurus.The Southern Cross carries cultural significance in many countries in the southern hemisphere. Beta Crucis (also called Becrux or Mimosa) is a bright star in the Southern Cross constellation, near Centaurus.

It is only slightly fainter than Mimosa lies at a distance of 280 light years from Earth. Before joining Encyclopaedia Britannica in 2007, he worked at the University of Chicago Press on the Astrophysical... Beta Crucis Jewel Box Cluster. July 31, 2015 by admin.
The cluster has an apparent magnitude of 4.2 and lies at an approximate distance of 6,440 light years from Earth. Their given spectral types are B0.5 III and B2V.The primary component is classified as a Beta Cephei variable.
It is the 20th brightest star in the night sky. Mimosa - β Crucis (beta Crucis) Mimosa, also designated as β Crucis (beta Crucis), is a variable and multiple hypergiant star in the constellation of Crux. The Kappa Crucis Cluster, also known as the Jewel Box and designated NGC 4755 in the Mimosa is located in Crux, the smallest constellation in the sky. In spite of its size, Crux is one of the most conspicuous southern constellations, and the Southern Cross, formed by the constellation’s brightest stars, plays an important role in many cultures south of the equator.The best known deep sky objects in the constellation are the Kappa Crucis Cluster, one of the youngest open clusters known, and the Coalsack Nebula, a dark cloud of dust and gas more than 30 light years across, that blocks some of the light of the Kappa Crucis Cluster stars. With an apparent visual magnitude of +1.63, this is the third-brightest star in the southern constellation of Crux and is listed 26th of the brightest stars in the night sky.
Although Mimosa is at roughly −60° declination, and therefore not visible north of 30° latitude, 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 of Centaurus. Gacrux /ˈɡækrʌks/, Gamma Crucis, is the nearest class M giant star to the Sun.
The estimated age of the system is 8 to 11 million years.The primary star, Beta Crucis A, has 16 solar masses, which seals its fate as a supernova in a few million years, and a radius 8.4 times that of the Sun.
It bore the traditional names Mimosa and the historical name Becrux /ˈbeɪkrʌks/. It's a Small size geocache, with difficulty of 1.5, terrain of 2. BETA CRUCIS 'BETA CRUCIS' is a 10 letter phrase starting with B and ending with S Synonyms, crossword answers and other related words for BETA CRUCIS.

With an apparent magnitude of 1.25, it is the second brightest star in Crux and the 20th brightest star in the sky. Beta Crucis is a binary of two B-type stars about 280 light-years from Earth.The primary is a pulsating variable star of the Beta Cephei type; its brightness changes by a few hundredths of a magnitude every four hours. The Coalsack Nebula can be seen between the cluster and The best time of year to observe the stars and deep sky objects in Crux is during the month of May. How many times larger is the radius of the Sun than that of the Earth?

The companion, Beta Crucis B, has an estimated mass 10 times that of the Sun.Both are class B stars, appearing blue-white in colour. Also known as Becrux, it is one of the four bright stars that form the Southern Cross, one of the most familiar asterisms in the southern sky.Beta Crucis is a spectroscopic binary star system composed of a pair of stars that complete an orbit every 5 years (1,828 ± 2.5 days) at a separation between 5.4 and 12 astronomical units. A line from the two "Pointers", Alpha Centauri through Beta Centauri, leads to within 1° north of this star.
