4086 Podalirius (1985 VK2) is a 90 km Jupiter Trojan discovered on November 9, 1985 by L. V. Zhuravleva at Nauchnyj. It is one of the fifty largest Jupiter Trojans.

Photometric observations of this asteroid during 1994 were used to build a light curve showing a rotation period of 10.43 ± 0.04 hours with a brightness variation of 0.13 ± 0.01 magnitude.^[2]
