It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude that fluctuates around 4.71.[2] This system lies approximately 254\u00a0light years from the Sun based on parallax, and it is drifting further away with a radial velocity of +19.4\u00a0km\/s.[4]The primary component is an Ap star on the main sequence with a stellar classification of A2VpSrCrEu,[3] where the suffix notation indicates abnormal abundances of strontium, chromium, and europium in the stellar atmosphere. It is an Alpha2 Canum Venaticorum variable; its apparent magnitude varies from 4.70 down to 4.75 with a period of 12.5 days.[3] A rotationally-modulated magnetic field has been measured, varying from \u221272\u00b19\u00a0G to 57\u00b19\u00a0G. It has an estimated rotation period of 5.98\u00b10.06\u00a0d, although this is in need of further confirmation.[10]The proper motion companion[11] is a magnitude 12.8 star at an angular separation of 6.7\u2033.[9]References[edit]^ a b c d e f g h Brown, A.
