SIMBAD data

HD 63399 is an orange hued star located in the southern constellation Puppis, the poop deck. It has an apparent magnitude of 6.45, [2] placing it near the limit for naked eye visibility. Based on parallax measurements from Gaia DR3, [1] the object is estimated to be 445 light years distant. It appears to be receding with a spectroscopic radial velocity of 28.5  km/s . [6] At its current distance, HD 63399 is diminished by 0.29 magnitudes due to interstellar dust. [13]

HD 63399 is a red giant star that is currently on the red giant branch, [3] fusing hydrogen in a shell around its core. It has a stellar classification of K1 III. [4] At present it has a mass ranging from 1.3 to 1.7 times the mass of the Sun, [8] [9] depending on the study. HD 63399 has expanded to 10.8 times its girth [10] and now radiates 54.8 times the luminosity of the Sun [6] from its swollen photosphere at an effective temperature of 4,761  K . [11] The star has an iron abundance 13% below solar levels, making it slightly metal deficient. [3]
