SIMBAD data

HD 37289, also known as HR 1916, is a solitary, [11] orange hued star located in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 5.61, [2] making it faintly visible to the naked eye under ideal conditions. Based on parallax measurements from the Gaia spacecraft, the object is estimated to be 308 light years distant. [1] It appears to be approaching the Sun, having a heliocentric radial velocity of −20.7  km/s . [5]

HD 37289 has a stellar classification of K5 III, [3] indicating that it is an evolved red giant. Gaia DR3 stellar evolution models place it on the red giant branch. [1] This means that it is currently fusing a hydrogen shell around an inert helium core. At present it has 3.3 times the mass of the Sun and at the age of 293 million years, [1] it has expanded to a radius of 13.6  R☉. [7] It radiates at 70 times the luminosity of the Sun [8] from its enlarged photosphere at an effective temperature of 4,360  K . [10] HD 37289 has been calculated to have a metallicity approximately around solar level. [10]
