11509 Thersilochos (/θərˈsɪləkəs/ thər-SIL-ə-kəs), provisional designation 1990 VL6, is a Jupiter trojan discovered on 15 November 1990, by Belgian astronomer Eric Elst at the ESO's La Silla Observatory in northern Chile. It measures approximately 57 kilometers in diameter.

Photometric observations of this asteroid during 2010 were used to build a light curve showing a rotation period of 17.367 ± 0.015 hours with a brightness variation of 0.27 ± 0.01 magnitude.[2]
