HD 25274, also known as HR 1241, is a solitary star[1] located in the northern circumpolar constellation Camelopardalis. It is faintly visible to the naked eye as a red hued point of light with an apparent magnitude of 5.86.[2] Gaia DR3 parallax measurements imply a distance of 597 light-years and it is currently drifting closer with a heliocentric radial velocity of Template:Val.[3] At its current distance, HD 25274's brightness is diminished by three-tenths of a magnitude due to interstellar extinction[4] and it has an absolute magnitude of −0.51.[5]

HD 25274 has a stellar classification of M0 III,[6] indicating that it is an evolved red giant. However, the Bright Star Catalog gives a hotter classification of K2 III.[7] The spectrophotometry-measured angular diameter, after correcting for limb darkening, is Template:Val.[8] At the estimated distance for HD 25274, this yields a physical radius 39.8 times that of the Sun.[9] It also has an empirical radius of Template:Solar radius[10] and Gaia DR3 models a larger radius.[11] The object radiates 762 times the luminosity of the Sun[11] from its enlarged photosphere at an effective temperature of Template:Val.[12] HD 25274 is metal deficient with an iron abundance 62% that of the Sun's ([Fe/H] = −0.21)[13] and it spins modestly with a projected rotational velocity of Template:Val.[14] HD 25274 is a field star of the HIP 21974 cluster.[15]
