Based on parallax measurements from Gaia DR3, the object is estimated to be 445 light years distant. It appears to be receding with a spectroscopic radial velocity of $$. At its current distance, HD 63399 is diminished by 0.29 magnitudes due to interstellar dust.

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