Quasi satellites are bodies in a particular configuration of a 1 : 1 mean motion resonance, one in which they librate about the longitude of their associated planet. We investigate numerically the stability of such orbits around the giant planets of our solar system. We find that test particles can remain on quasi-satellite orbits around Uranus and Neptune for times up to 109 yr in some cases, though only at low inclinations relative to their accompanying planet and over a restricted range of… Expand

Figures from this paper

We conduct a systematic survey of the regions in which distant satellites can orbit stably around the four giant planets in the solar system, using orbital integrations of up to 109 yr. In contrastExpand
Stability limits for the quasi-satellite orbit
An asteroid moving around the Sun having approximately the same mean motion and mean longitude as a planet, but a different eccentricity, circles the planet like a retrograde satellite even when theExpand
Discovery of 12 satellites of Saturn exhibiting orbital clustering
The discovery of 12 irregular satellites of Saturn is reported, along with the determinations of their orbits, indicating that most of the irregular moons are collisional remnants of larger satellites that were fragmented after capture, rather than being captured independently. Expand
Evaluating the Signatures of the Mean Motion Resonances in the Solar System
The characteristics of the resonant disturbing function for an asteroid perturbed by a planet in circular orbit are discussed. The location of the libration centers and their dependence with theExpand
On the co-orbital motion in the planar restricted three-body problem: the quasi-satellite motion revisited
In the framework of the planar and circular restricted three-body problem, we consider an asteroid that orbits the Sun in quasi-satellite motion with a planet. A quasi-satellite trajectory is aExpand
Jupiter's outer satellites and Trojans
Jupiter’s irregular satellites possess large, eccentric and highly inclined orbits. They are conventionally considered separately from the temporarily captured satellites and the Trojans (the latterExpand
Dynamics of two planets in co-orbital motion
We study the stability regions and families of periodic orbits of two planets locked in a co-orbital configuration. We consider different ratios of planetary masses and orbital eccentricities; weExpand
On the Inclination Distribution of the Jovian Irregular Satellites
Irregular satellites—moons that occupy large orbits of significant eccentricity e and/or inclination I—circle each of the giant planets. The irregulars often extend close to the orbital stabilityExpand
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 theExpand
An efficient, low-velocity, resonant mechanism for capture of satellites by a protoplanet
Abstract Numerical simulations of the gravitational scattering of planetesimals by a protoplanet reveal that a significant fraction of scattered planetesimals can become trapped as so-calledExpand


Orbital Stability of Planetary Quasi-Satellites
An object having the same mean motion and mean longitude, but different eccentricity than a planet, appears to circle the planet like a retrograde moon. If the distance is large enough such that theExpand
Dynamical Stability in the Outer Solar System and the Delivery of Short Period Comets
Test particle stability in the outer solar system is surveyed. Roughly 7000 test particles are numerically integrated for durations ranging from 20 to 800 million yr. The initial conditions of theExpand
A numerical exploration of the evolution of Trojan-type asteroidal orbits
Numerical N-body integrations have been conducted to study the stability of orbits of asteroids, which are co-orbital with the major planets. In Jupiter's case such celestial bodies are theExpand
A possible long-lived belt of objects between Uranus and Neptune
Recent discoveries of objects orbiting beyond Neptune have emphasized that our understanding of the distribution and dynamics of material in the outer Solar System is very incomplete. ThisExpand
A new dynamical class of object in the outer Solar System
Some three dozen objects have now been discovered beyond the orbit of Neptune and classified as members of the Kuiper belt—a remnant population of icy planetesimals that failed to be incorporatedExpand
From the Kuiper Belt to Jupiter-Family Comets: The Spatial Distribution of Ecliptic Comets☆
Abstract We present numerical orbital integrations of thousands of massless particles as they evolve from Neptune-encountering orbits in the Kuiper belt for up to 1 Gyr or until they either impact aExpand
Stability of Periodic Orbits in the Restricted Problem
Critical orbits, separating stable from unstable periodic orbits, have been computed for the six main families f, g, h, i, l, m and for all values of the mass ratio μ. The results are given by tablesExpand
Symplectic maps for the N-body problem.
The present study generalizes the mapping method of Wisdom (1982) to encompass all gravitational n-body problems with a dominant central mass. The rationale for the generalized mapping method isExpand
