Plutinos are Kuiper belt objects that share the 3:2 Neptune resonance with Pluto. The long-term stability of Plutino orbits depends on their eccentricity. Plutinos with eccentricities close to Pluto's (fractional eccentricity difference Δe/eP = |e - eP|/eP 0.1) can be stable because the longitude difference librates, in a manner similar to the tadpole and horseshoe libration in co-orbital satellites. Plutinos with Δe/eP 0.3 can also be stable; the longitude difference circulates and close… Expand

Close Approaches of Trans-Neptunian Objects to Pluto Have Left Observable Signatures on Their Orbital Distribution
It is shown that in addition to four outer planets (Jupiter to Neptune) Pluto should be also taken into account in studies of the orbital dynamics in the trans-Neptunian region. Pluto's effect is… Expand
The Effect of Neptune's Accretion on Pluto and the Plutinos
The peculiar relationship of Pluto to Neptune, its resonances and high eccentricity and inclination, have led to the theory that the relationship arose from the migration of the outer planets,… Expand
Plutino (15810) 1994 JR1, an accidental quasi-satellite of Pluto
In the Solar system, quasi-satellites move in a 1:1 mean motion resonance going around their host body like a retrograde satellite but their mutual separation is well beyond the Hill radius and the… Expand
Neptune's Orbital Migration Was Grainy, Not Smooth
The Kuiper belt is a population of icy bodies beyond the orbit of Neptune. The complex orbital structure of the Kuiper belt, including several categories of objects inside and outside of resonances… Expand
The characteristics of orbital distribution of Kuiper belt objects
Abstract A statistical analysis of the orbital semi-major axes of Kuiper belt objects (KBOs) shows that the mass weighted mean of the heliocentric distances of 528 trans-Neptunian objects (TNOs) is… Expand
The contribution of plutinos to the Centaur population
Abstract We present a study of the dynamical evolution of plutinos recently escaped from the resonance through numerical simulations. It was shown in previous works the existence of weakly chaotic… Expand
CHAOTIC DIFFUSION OF RESONANT KUIPER BELT OBJECTS
We carried out extensive numerical orbit integrations to probe the long-term chaotic dynamics of the two strongest mean-motion resonances of Neptune in the Kuiper Belt, the 3:2 (Plutinos) and 2:1… Expand
The orbit evolution of 32 plutinos over 100 million year
The orbits of thirty two plutinos that are presently in the 3:2 mean motion resonance with Neptune have been integrated numerically and accurately to 10 8 years into the future. Fourteen of them are… Expand
Neptune's 5:2 Resonance in the Kuiper Belt
Observations of Kuiper belt objects (KBOs) in Neptune's 5:2 resonance present two puzzles: this third order resonance hosts a surprisingly large population, comparable to the prominent populations of… Expand
Dynamical evolution of escaped plutinos, another source of Centaurs
Context. Weakly chaotic orbits that diffuse very slowly have been found to exist in the plutino population. These orbits correspond to long-term plutino escapers and represent the plutinos presently… Expand
