(696315) Petraios Centaur
Discovered on 4 April 2016 by Mount Lemmon Survey at Mount Lemmon.
The centaur Petraios took part in the battle at the wedding of Pirithous, a symbolic clash between primal chaos and social order. His name means “rocky”, evoking strength and stability. As Ovid tells, Petraios fell while grappling with the rooted Earth. Like this minor planet, he marks the edge between structure and upheaval.Naming citation (WGSBN Bull. 5, #19, 13), IAU / Minor Planet Center, via NASA/JPL
