53 Camelopardalis is a

semimajor axis and i is the orbital inclination.[7]

The visible component is a well-studied magnetic

Ap star[7] with a stellar classification of A3VpSrSiCrEu[5] and a visual magnitude of 6.3.[4] The magnetic field topology of 53 Camelopardalis is complex, and is accompanied by abundance variations across the surface of elements like silicon, calcium, titanium, iron, and neodymium.[7] It is classified as an Alpha2 Canum Venaticorum type variable star and the combined brightness of the system varies from magnitude +6.00 down to +6.05 with a rotationally-modulated period of 8.0278 days.[6]

The primary has 2.1 times the

luminosity of the Sun from its photosphere at an effective temperature of 8,400 K.[7]
