This object is barely visible to the naked eye as a dim, blue star with an apparent visual magnitude of 6.232. It is approaching the Earth with a heliocentric radial velocity of 4.0Шаблон:± km/s.[1]

The star system is a visual binary with a 3.29″ projected separation,[2] identified as such in 2002.[3] The larger star, HD 83368A, is a pulsating variable of a rapidly oscillating Ap type. It has a single yet strongly distorted dipole pulsation mode with a frequency of 1427 µHz.[4] The primary star is chemically peculiar, exhibiting spots of enhanced concentrations of lithium, europium and oxygen.[2]
