It is visible to the naked eye as a faint, white-hued point of light with a combined apparent visual magnitude of 4.76.[2] The system is located approximately 183\u00a0light years away from the Sun based on parallax.[1] It is a member of the Hyades Supercluster.[11]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\u00a0AU from the star with a mean temperature of 95\u00a0K.[7] It has one visual companion at an angular separation of about 30\u2033 and magnitude 13.7.[12][13]References[edit]^ a b c d e f Brown, A.
