HD 129445 (HIP 72203; LTT 5856) is a star located in the southern constellation Circinus. It has an apparent magnitude of 8.80,^[2] making it faintly visble in binoculars but not to the naked eye. The object is located relativelyt 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.^[1] It has an absolute magnitude of +4.73,^[2] which is similar to the Sun's absolute magnitude of 4.83.
