HD 112014 is a star system[7] in the northern constellation of Camelopardalis. It is dimly visible as a point of light with an apparent visual magnitude of 5.92.[2] The distance to this system is approximately 406 light years based on parallax measurements.[1]

The stars HD 112028 and HD 112014 were identified as a double star by F. G. W. Struve in 1820, and are listed as WDS 12492+8325 A and B, respectively, in the Washington Double Star Catalog.[8] The binary nature of component B, or HD 112014, was discovered by J. S. Plaskett in 1919. It is a double-lined spectroscopic binary with an orbital period of 3.29 days and an eccentricity (ovalness) of 0.04.[5] They are separated by 0.0759 AU (11.35 Gm).[6] Both components are A-type main-sequence stars.[3]
