The WGSN states that in the case of multiple stars the name should be understood to be attributed to the
brightest component by
visual brightness.
Because the relative motion of the
brighter components implied actual physical association rather than coincidental
visual alignment, Félix Savary (1797 - 1841) was inspired to calculate the first orbit ever for a «double star» by applying Newton's «laws of gravity» in 1828, whose solution was subsequently provided by Herschel in 1829.
Its
brightest star, HD 93206 or QZ Carinae, is an eclipsing variable, varying between
visual magnitudes 6.16 and 6.49, the main
component being of spectral type O9III or B0Ib:; it is approaching us at about 16 km / sec.
