HD 24480 is a multiple[7] star system in the northern constellation of Camelopardalis. The brighter component is a giant star with a stellar classification of K4III and an apparent magnitude of 5.20.[3] The companion is a hotter, A-[4] or B-type star that is a suspected spectroscopic binary system.[7] The visible pair have an angular separation of 1.71 arcseconds.[3]
