HD 112028 is an evolved star in the northern constellation of Camelopardalis. It has spectral peculiarities that have been interpreted as a shell, and also relatively weak magnesium and silicon lines. Its spectral class has been variously assigned between B9 and A2, and its luminosity class between a subgiant and bright giant.[11]

At an angular separation of 21.47″ is the slightly fainter spectroscopic binary HD 112014, consisting of a pair of A-type main sequence stars. HD 112028 and HD 112014 together are known as the binary star Struve 1694.[12]
