This object is a highly luminous

luminosity of the Sun from its enlarged photosphere at an effective temperature of 6,300 K.[8]

Several

visual companions beside the primary have been recorded. B, with magnitude 12.1 and separation 31.6", has its own companion, E, with magnitude 14.3 and separation 7.7". Additionally, C has magnitude 13.2 and separation 55.7", and D has magnitude 13.8 and separation 22.8".[14]
