    (182294) 2001 KU76 (provisional designation 2001 KU76) is a trans-Neptunian object (TNO) that has a possible 6:11 resonance with Neptune. [2] [3]

    Contents

    Assuming a generic TNO albedo of 0.09, it is about 211 km in diameter. [5] The assumed diameter of this object makes it a possible dwarf planet. [6]

    Resonance

    Simulations by Lykawka in 2007 show that 2001 KU76 may be librating in the 6:11 resonance with Neptune. [2] Buie classifies it as probably in resonance, although some possible orbits do not librate. [3] 2001 KU76 has a semi-major axis of 45 AU and an orbital period of about 302 years. [1]

    It has been observed 29 times over 6 years and has an orbit quality code of 4. [1]

    A trans-Neptunian object (TNO), also written transneptunian object, is any minor planet in the Solar System that orbits the Sun at a greater average distance than Neptune, which has an orbital semi-major axis of 30.1 astronomical units (au).

    <span class="nowrap">(148209) 2000 CR<sub>105</sub></span>

    (148209) 2000 CR105 is a trans-Neptunian object and the tenth-most-distant known object in the Solar System as of 2015. Considered a detached object, it orbits the Sun in a highly eccentric orbit every 3,305 years at an average distance of 222 astronomical units (AU).

    In astronomy, a resonant trans-Neptunian object is a trans-Neptunian object (TNO) in mean-motion orbital resonance with Neptune. The orbital periods of the resonant objects are in a simple integer relations with the period of Neptune, e.g. 1:2, 2:3, etc. Resonant TNOs can be either part of the main Kuiper belt population, or the more distant scattered disc population.

    <span class="mw-page-title-main">Detached object</span> Dynamical class of minor planets

    Detached objects are a dynamical class of minor planets in the outer reaches of the Solar System and belong to the broader family of trans-Neptunian objects (TNOs). These objects have orbits whose points of closest approach to the Sun (perihelion) are sufficiently distant from the gravitational influence of Neptune that they are only moderately affected by Neptune and the other known planets: This makes them appear to be "detached" from the rest of the Solar System, except for their attraction to the Sun.
