The brighter component is an A-type main-sequence star with a stellar classification of A0Va.^[3] It may form a binary system of two roughly equal stars.^[10] An infrared excess suggests there is a debris disk orbiting 46.3 AU from the star with a mean temperature of 95 K.^[7] It has one visual companion at an angular separation of about 30″ and magnitude 13.7.^[12][13]
