(316179) 2010 EN₆₅ is a trans-Neptunian object orbiting the Sun. However, with a semi-major axis of 30.8 AU, the object is actually a jumping Neptune trojan, co-orbital with Neptune, as the giant planet has a similar semi-major axis of 30.1 AU. The body is jumping from the Lagrangian point L₄ into L₅ via L₃.^[4] As of 2016^[update], it is 54 AU from Neptune. By 2070, it will be 69 AU from Neptune.^[7]

2010 EN₆₅ was discovered on 7 March 2010, by David L. Rabinowitz and Suzanne W. Tourtellotte using the 1.3-meter Small and Medium Research Telescope System (SMARTS) at Cerro Tololo Observatory in Chile.^[1]

2010 EN₆₅ follows a rather eccentric orbit (0.31) with a semi-major axis of 30.72 AU and an inclination of 19.3º.^[3] Its orbit is well determined with images dating back to 1989.

2010 EN₆₅ is a quite large minor body with an absolute magnitude of 7.17 and an estimated diameter of 176 kilometers (109 miles) based on an assumed albedo of 0.08.^[5][6]

2010 EN₆₅ is another co-orbital of Neptune, the second brightest after the quasi-satellite (309239) 2007 RW10. 2010 EN₆₅ is currently transitioning from librating around Lagrangian point L4 to librating around L5.^[4] This unusual trojan-like behavior is termed "jumping trojan".^[8]

This minor planet was numbered by the Minor Planet Center on 7 February 2012 (M.P.C. 78220).^[9] As of 2021^[update], it has not been named.^[2] If named, it will follow the naming scheme already established with 385571 Otrera and 385695 Clete, which is to name these objects after figures related to the Amazons, an all-female warrior tribe that fought in the Trojan War on the side of the Trojans against the Greek.^[10]
