2357 Phereclos (1981 AC) is a 95 km Jupiter Trojan discovered on January 1, 1981 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory, it was named after Phereclus.

Photometric observations of this asteroid during 2010 were used to build a light curve showing a rotation period of 14.394 ± 0.012 hours with a brightness variation of 0.09 ± 0.01 magnitude.^[2]
