26 Camelopardalis is a single [8] star in the northern constellation of Camelopardalis, positioned next to the southern constellation boundary with Auriga. It is a suspected variable star [9] that is dimly visible to the naked eye with a peak apparent visual magnitude of +5.93. [2] This object is located at a distance of 197  light years from the Sun based on parallax, [1] and is drifting further away with a radial velocity of +21 km/s. [2]

This is a white-hued A-type main-sequence star with a stellar classification of A4Vn, [4] where the 'n' notation indicates "nebulous" absorption lines due to rapid rotation. It is an estimated 345 [5]  million years old and is spinning with a projected rotational velocity of 249 km/s. [3] The star has 1.80 [3] times the mass of the Sun and is radiating 13 times the Sun's luminosity from its photosphere at an effective temperature of 7,798 K. [3]
