=== Orbital characteristics === [[File:Plutino distributions and sizes.png|thumb|The distribution of Plutinos, and relative sizes, drawn 1 million times larger.]] While the majority of plutinos have relatively low [[orbital inclination]]s, a significant fraction of these objects follow orbits similar to that of Pluto, with inclinations in the 10–25° range and eccentricities around 0.2–0.25; such orbits result in many of these objects having [[perihelion|perihelia]] close to or even inside Neptune's orbit, while simultaneously having [[aphelion|aphelia]] that bring them close to the main [[Kuiper belt]]'s outer edge (where objects in a 1:2 resonance with Neptune, the Twotinos, are found). The orbital periods of plutinos cluster around 247.3 years (1.5 × Neptune's orbital period), varying by at most a few years from this value. Unusual plutinos include: * [[List of unnumbered trans-Neptunian objects: 2005#2005 TV189|{{mp|2005 TV|189}}]], which follows the most highly inclined orbit (34.5°) *{{mpl|(15875) 1996 TP|66}}, which has the most elliptical orbit (its eccentricity is 0.33), with the perihelion halfway between Uranus and Neptune *{{mpl|(470308) 2007 JH|43}} following a quasi-circular orbit * [[List of unnumbered trans-Neptunian objects: 2002#2002 VX130|{{mp|2002 VX|130}}]] lying almost perfectly on the [[ecliptic]] (inclination less than 1.5°) *[[15810 Arawn]], a [[quasi-satellite]] of Pluto<ref name=analemma>{{cite journal |title=The analemma criterion: accidental quasi-satellites are indeed true quasi-satellites |first1=Carlos |last1=de la Fuente Marcos |last2=de la Fuente Marcos |first2=Raúl |journal=[[Monthly Notices of the Royal Astronomical Society]] |date=2016 |volume=462 |issue=3 |pages=3344–3349 |arxiv=1607.06686 |doi=10.1093/mnras/stw1833 |doi-access=free |bibcode=2016MNRAS.462.3344D}}</ref> See also the comparison with the [[cubewano#Distribution|distribution of the cubewanos]].
