    Discovery

    2010 EU65 was discovered on March 13, 2010 by David L. Rabinowitz and S. Tourtellotte, observing from La Silla, Chile.[2]

    Orbit

    2010 EU65 follows a low eccentricity orbit (0.060) with a semi-major axis of 19.30 AU.[4] This object also has moderate orbital inclination (14.8º).[4] 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.[1]

    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.[1]

    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.[3]

    gollark: You know, that sort of definition includes fire and stars and such.
    gollark: Too bad. Do so.
    gollark: Exactly. Have you made the train generator yet? You have about 4.7 weeks I think.
    gollark: If it's "false", how come it's true?
    gollark: 2021-06-09 better, however.
