, ▁r anging ▁in ▁magnitude ▁from ▁ 4 . 7 4 ▁to ▁ 4 . 9 6 . ▁Based ▁upon ▁an ▁annual ▁par alla x ▁shift ▁of ▁ ▁as ▁seen ▁from ▁Earth ' s ▁orbit , ▁it ▁is ▁located ▁around ▁ 4 7 0 ▁light ▁years ▁from ▁the ▁Sun . ▁It ▁is ▁a ▁candidate ▁member ▁of ▁the ▁Upper ▁Sc or pi us ▁group ▁of ▁the ▁Sc or pi us - C enta urus ▁Association , ▁with ▁the ▁former ▁having ▁an ▁age ▁of ▁about ▁ 1 1 ▁million ▁years . ▁ ▁This ▁is ▁a ▁main ▁sequence ▁Be ▁star ▁with ▁a ▁stell ar ▁classification ▁of ▁B 3   V sh , ▁although ▁it ▁has ▁been ▁various ly ▁class ed ▁as ▁B 3 V , ▁B 5 III p ▁shell ▁He - n , ▁B 6 p ▁shell , ▁B 4 III , ▁B 3 IV : e - shell , ▁and ▁B 3 ▁shell ▁by ▁different ▁sources . ▁As ▁is ▁the ▁norm ▁for ▁a ▁shell ▁star , ▁it ▁is ▁spin ning ▁very ▁rapidly ▁with ▁a ▁project ed ▁rot ational ▁velocity ▁of ▁ 4 0 0   km / s ▁− ▁matching ▁or ▁exceed ing ▁ 8 0 % ▁of ▁the ▁critical ▁velocity . ▁This ▁is ▁giving ▁the ▁star ▁a ▁pron ounced ▁ob late ▁shape ▁with ▁an ▁equ atorial ▁bul ge ▁that ▁is ▁estimated ▁to ▁be ▁ 4 3 % ▁larger ▁than ▁the ▁polar ▁radius . ▁It ▁has ▁six ▁times ▁the ▁mass ▁of ▁the ▁Sun ▁and ▁four ▁times ▁the ▁Sun ' s ▁radius . ▁The ▁star
