HD 134335 is a giant star in the northern constellation of Boötes. 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 based on parallax measurements,[2] and is drifting closer with a heliocentric radial velocity of −18 km/s.[3] It may approach as close as Template:Cvt in about 7.6 million years.[1]
The stellar classification of HD 134335 is K1III,[4] matching a K-type giant star that has exhausted the supply of hydrogen at its core and expanded. It is radiating 127 times the luminosity of the Sun from its photosphere at an effective temperature of 4,409 K.[5]
