HD 32356, also designated as HR 1624, is an astrometric binary[13] located in the northern circumpolar constellation Camelopardalis, the giraffe, near β Camelopardalis. The visible component is faintly visible to the naked eye as an orange-hued star with an apparent magnitude of 5.99.[2] Gaia DR3 parallax measurements imply a distance of 557 light-years[1] and it is currently drifting closer with a heliocentric radial velocity of −45.2 km/s.[5] At its current distance, HD 32356's brightness is diminished by an interstellar extinction of 0.29 magnitudes[14] and it has an absolute magnitude of +0.23.[6]

The visible component has a stellar classification of K5 II,[3] indicating that it is an evolved K-type bright giant that has ceased hydrogen fusion at its core and left the main sequence. It has 1.18 times the mass of the Sun[7] but at the age of 4.27 billion years,[9] it has expanded to 30.67 times the radius of the Sun.[8] It radiates 300 times the luminosity of the Sun[1] from its enlarged photosphere at an effective temperature of 4,111 K.[10] HD 32356 A is metal deficient with an iron abundance roughly half of the Sun's[10] and it spins too slowly for its projected rotational velocity to be measured accurately.[11]
