Astrometric binary in Camelopardalis
HD 32356 , also designated asHR 1624 , is anastrometric binary [ 13] circumpolar constellation Camelopardalis , the giraffe, nearβ Camelopardalis . The visible component is faintly visible to thenaked eye as an orange-huedstar with anapparent magnitude of 5.99.[ 3] Gaia DR3 parallax measurements imply a distance of 557light-years [ 2] radial velocity ofkm/s [ 6] interstellar extinction of 0.29magnitudes [ 14] absolute magnitude of +0.23.[ 1]
The visible component has astellar classification of K5 II,[ 4] evolved K-type bright giant that has ceasedhydrogen fusion at itscore and left themain sequence . It has 1.18 times themass of the Sun [ 7] billion years ,[ 9] radius of the Sun .[ 8] luminosity of the Sun [ 2] photosphere at aneffective temperature ofK [ 10] iron abundance roughly half of theSun 's[ 10] projected rotational velocity to be measured accurately.[ 11]
