Discovery
2010 EU65 was discovered on March 13, 2010 by David L. Rabinowitz and S. Tourtellotte, observing from La Silla, Chile.
Orbit
2010 EU65 follows a low eccentricity orbit (0.060) with a semi-major axis of 19.30 AU. This object also has moderate orbital inclination (14.8º). 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.
Physical properties
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.
Uranus horseshoe candidate
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.
