The object is located relatively close at a distance of 219 light-years based on Gaia DR3 parallax measurements but it is drifting away with a spectroscopic radial velocity of 8.56 km/s.
HD 129445 has a stellar classification of G6 V,[3] indicating that it is an ordinary G-type main-sequence star like our Sun, albeit a bit cooler.
[5] It radiates 1.23 times the luminosity of the Sun from its photosphere at an effective temperature of 5,605 K,[5] giving it a yellow hue when viewed in the night sky.
HD 129445 is extremely metal enriched with an iron abundance more than twice of that of the Sun's[4] and it spins slowly with a projected rotational velocity of 1.4 km/s.
[4] The star was observed by the Magellan Planet Search Program due to its absolute visual magnitude and high metallicity.
