385571 Otrera (provisional designation: (385571) 2004 UP10) is a Neptune trojan discovered by Scott S. Sheppard and Chadwick A. Trujillo in 2004. It was the second such body to be discovered. It has the same orbital period as Neptune and orbits at the L4 Lagrangian point about 60 degrees ahead of Neptune.
Otrera is the first Neptune Trojan to be named. It is named after the first queen of the Amazons. Otrera was involved with Ares and is the mother of the Amazons queen Penthesilea, who led the Amazons in the Trojan war.
The Neptune Trojan naming scheme is to name these objects after things related to the Amazons, which is an all female warrior tribe that fought in the Trojan war on the side of the Trojans.
