Astrometric binary in Camelopardalis.
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]
