4 Camelopardalis is a probable

″ per year.[12] The system's proper motion makes it a candidate for membership in the IC 2391 supercluster.[13] They are moving away from the Earth with a heliocentric radial velocity of 22.5 km/s.[5]

The brighter member, designated component A, is classified as an

Sun's luminosity from its photosphere at an effective temperature of 7,700 K.[9]

There is a faint, magnitude 9.49 companion at an

′ away, is probably unrelated.[16]
