    (35671) 1998 SN165 is a trans-Neptunian object. It was discovered on 23 September 1998, by A. Gleason at Steward Observatory.

    It was originally classified as a plutino with a 2:3 mean-motion resonance with Neptune,[6] but further observations have established that it is a cubewano—a member of the classical Kuiper belt.[1]

    With an estimated size of 393+39
    −38     km    ,[4] (35671) 1998 SN165 is a possible dwarf planet.

    Notes
