Шаблон:Mp 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 Шаблон:L4 into Шаблон:L5 via Шаблон:L3. Шаблон:As of, it is 54 AU from Neptune. By 2070, it will be 69 AU from Neptune.

Discovery

Шаблон:Mp 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.

Orbit

Шаблон:Mp follows a rather eccentric orbit (0.31) with a semi-major axis of 30.72 AU and an inclination of 19.3º. Its orbit is well determined with images dating back to 1989.

Physical properties

Шаблон:Mp is a quite large minor body with an absolute magnitude of 7.17 and an estimated diameter of Шаблон:Convert based on an assumed albedo of 0.08.

Jumping trojan

Шаблон:Mp is another co-orbital of Neptune, the second brightest after the quasi-satellite Шаблон:Mpl. Шаблон:Mp is currently transitioning from librating around Lagrangian point L4 to librating around L5. This unusual trojan-like behavior is termed "jumping trojan".

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 7 February 2012 (Шаблон:Small). Шаблон:As of, it has not been named. 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.
