Abstract The stability of orbits in the transneptunian region is numerically computed. It is found that, in analogy to the asteroid belt, there exist many chaotic layers associated with thin mean-motion resonances. These are either moderate- and high-order resonances with Neptune or three-body resonances with Neptune and Uranus. The orbital eccentricity chaotically increases at the thin resonances, allowing some Kuiper Belt objects to be slowly transferred to Neptune-crossing orbits. The… 
Asteroids in the 2 : 1 resonance with Jupiter: dynamics and size distribution
The 2 : 1 mean motion resonance with Jupiter in the main asteroid belt is associated to one of the largest Kirkwood gaps: the so-called Hecuba gap. Centred at about 3.3 au, the Hecuba gap is
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
Resonant motion of trans-Neptunian objects in high-eccentricity orbits
A substantial fraction of the Edgeworth-Kuiper belt objects are presently known to move in resonance with Neptune (the principal commensurabilities are 1/2, 3/5, 2/3, and 3/4). We have found that
Resonance Occupation in the Kuiper Belt: Case Examples of the 5:2 and Trojan Resonances
As part of our ongoing Deep Ecliptic Survey (DES) of the Kuiper belt, we report on the occupation of the 1 : 1 (Trojan), 4 : 3, 3 : 2, 7 : 4, 2 : 1, and 5 : 2 Neptunian mean motion resonances (MMRs).
Three dimensional periodic orbits in exterior mean motion resonances with Neptune
In the framework of the three dimensional restricted three-body problem we study the dynamics of the exterior mean motion resonances with Neptune. The basis of our study is the computation of
Stability of Neptune’s Distant Resonances in the Presence of Planet Nine
Trans-Neptunian Objects (TNOs) in the scattered disk with 50 ≲ a ≲ 100 au are thought to cluster near Neptune’s n:1 resonances (e.g., 3:1, 4:1, and so on). While these objects spend lengthy periods
Retrograde periodic orbits in 1/2, 2/3 and 3/4 mean motion resonances with Neptune
We study planar and three-dimensional retrograde periodic orbits, using the model of the restricted three-body problem (RTBP) with the Sun and Neptune as primaries and focusing on the dynamics of


Mean Motion Resonances in the Trans-neptunian Region
The stability of the 2:3 mean motion resonance with Neptune is systematically explored and compared to the observed resonant population. It is shown that orbits with small and moderate amplitudes of
The Resonant Structure of the Kuiper Belt and the Dynamics of the First Five Trans-Neptunian Objects
Abstract By means of simple analytic models and numerical integrations, we explore the resonant structure of the Kuiper belt. We find that the inner order-one mean motion resonances with Neptune are
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
Three-Body Mean Motion Resonances and the Chaotic Structure of the Asteroid Belt
We discuss the existence and the properties of a new type of mean motion resonance populated by a large number of asteroids, the resonant angle being defined as a linear combination (with integer
On the Asteroidal Population of the First-Order Jovian Resonances
Abstract The frequency map analysis was applied to the fairly realistic models of the 2/1, 3/2, and 4/3 jovian resonances and the results were compared with the asteroidal distribution at these
On the Origin of Chaos in the Asteroid Belt
We consider the effect of gravitational perturbations from Jupiter on the dynamics of asteroids, when Jupiter is itself perturbed by Saturn. The presence of Saturn introduces a number of additional
Chaotic Diffusion and the Origin of Comets from the 2/3 Resonance in the Kuiper Belt
Abstract The dynamical structure of the 2/3 resonance at small inclination is explored using numerical integrations of test particles to compute the evolution of proper elements with time. The basic
Numerous Weak Resonances Drive Asteroids toward Terrestrial Planets Orbits
A systematic exploration of the chaotic structure of the asteroid belt is presented, first taking into account only the perturbations provided by the four giant planets and then including also the
Large Scattered Planetesimals and the Excitation of the Small Body Belts
Abstract We study the dynamical excitation that large planetesimals, scattered either by Neptune or Jupiter, could have provided to the primordial Edgeworth–Kuiper belt and the asteroid belt. Using
