2010 EU65, also written as 2010 EU65, is a minor body classified as centaur by the Minor Planet Center upon discovery. [1] The object is also a promising Uranus horseshoe librator candidate.[2]


2010 EU65 was discovered on March 13, 2010 by David L. Rabinowitz and S. Tourtellotte, observing from La Silla, Chile.[1]


2010 EU65 follows a low eccentricity orbit (0.060) with a semi-major axis of 19.30 AU.[1] This object also has moderate orbital inclination (14.8º).[1] Unfortunately, its orbit is not well determined as it is currently (September 2015) based on 26 observations with a data-arc span of 85 days.[3]

Physical properties[edit]

2010 EU65 is a medium size minor body with an absolute magnitude of 9.1 which gives a characteristic diameter of 28–90 km for an assumed albedo in the range 0.5-0.05.[3]

Uranus horseshoe candidate[edit]

Based on its current heliocentric orbit, 2010 EU65 follows a horseshoe orbit around Uranus' L3 point. Giving the fact that its orbit is, at present, poorly determined, the object is a promising Uranus horseshoe orbiter candidate.[2]
