It has an apparent magnitude of 5.73, making it faintly visible to the naked eye under ideal conditions. Based on Gaia DR3 parallax measurements, the object is located 539 light years away. It appears to be drifting away from the Solar System, having a heliocentric radial velocity of . This is an evolved giant star that is currently on the red giant branch, fusing hydrogen in a shell around an inert helium core. It has a stellar classification of G8 III. HD 34266 is calculated to be 490 million years old, almost 10 times younger than the Sun. However, it already left the main sequence due to a mass of . HD 34266 has expanded to 16.2 times the Sun's girth and now radiates 144 times the luminosity of the Sun from its photosphere at an effective temperature of . HD 34266 has a near solar metallicity and spins modestly with a projected rotational velocity of . References
