22 Camelopardalis is a

apparent visual magnitude of 7.03,[2] which is below the normal limit for visibility with the naked eye. This object is moving further from the Earth with a mean heliocentric radial velocity of +10 km/s.[4] Eggen (1991) listed it as a member of the IC 2391 supercluster.[8] It has also been catalogued as a member of the Hyades group. However, Griffin (2005) suggests it belongs to neither.[5]

This is a single-lined

semimajor axis and i is the orbital inclination
to the line of sight from the Earth. This value provides a lower bound on the true semimajor axis of their orbit.

The visible component is an

Sun's luminosity from its photosphere at an effective temperature of 6,732 K.[6]
