**HD 134335** is a [giant star](/source/Giant_star) in the northern [constellation](/source/Constellation) of [Boötes](/source/Bo%C3%B6tes). As a sixth magnitude star,[3] it is dimly visible to the naked eye under favorable viewing conditions. It is located at a distance of approximately 478 [light years](/source/Light_year) based on [parallax](/source/Stellar_parallax) measurements,[2] and is drifting closer with a heliocentric [radial velocity](/source/Radial_velocity) of −18 km/s.[3] It may approach as close as 37.3 ly (11.43 pc) in about 7.6 million years.[1]

The [stellar classification](/source/Stellar_classification) of HD 134335 is K1III,[4] matching a [K-type](/source/K-type_star) [giant star](/source/Giant_star) that has exhausted the supply of hydrogen at its [core](/source/Stellar_core) and expanded. It is radiating 127 times the luminosity of the Sun from its [photosphere](/source/Photosphere) at an [effective temperature](/source/Effective_temperature) of 4,409 K.[5]
