    3564 Talthybius is a Jupiter Trojan asteroid that orbits in the L4 Lagrangian point of the Sun-Jupiter system, in the "Greek Camp" of Trojan asteroids. It was named after the Greek hero Talthybius, who was a herald during the Trojan War. It was discovered by Edward L. G. Bowell on October 15, 1985 in Flagstaff, Arizona at the Anderson Mesa station of the Lowell Observatory.

    Photometric observations of this asteroid during 1994 were used to build a light curve showing a rotation period of 40.59 ± 0.13 hours with a brightness variation of 0.38 ± 0.01 magnitude.[1]
