Burbanks and Stephen Wiggins and David Farrelly},  journal={Nature},  year={2003},  volume={423},  pages={264-267},  url={https://api.semanticscholar.org/CorpusID:16382419}}
It is shown that irregular satellites are captured in a thin spatial region where orbits are chaotic, and that the resulting orbit is either prograde or retrograde depending on the initial energy.

Chaotic Capture of a Retrograde Moon by Venus and the Reversal of Its Spin

Planets are surrounded by fractal surfaces (traditionally called Hill spheres), separating the inner zones of long-term stable orbital motion of their satellites from the outer space where the…

Capture and escape in the elliptic restricted three‐body problem

Several families of irregular moons orbit the giant planets. These moons are thought to have been captured into planetocentric orbits after straying into a region in which the gravitation of the…

THE IRREGULAR SATELLITES: THE MOST COLLISIONALLY EVOLVED POPULATIONS IN THE SOLAR SYSTEM

The known irregular satellites of the giant planets are dormant comet-like objects that reside on stable prograde and retrograde orbits in a realm where planetary perturbations are only slightly…

Discovery of five irregular moons of Neptune

The discovery of five exceedingly faint moons of Neptune, two with prograde and three with retrograde orbits, which were presumably captured by Neptune.

TRANSIENT CHAOS AND FRACTAL STRUCTURES IN PLANETARY FEEDING ZONES

The circular restricted three-body problem is investigated in the context of accretion and scattering processes. In our model, a large number of identical non-interacting mass-less planetesimals are…

TEMPORARY CAPTURE OF ASTEROIDS BY A PLANET: DEPENDENCE OF PROGRADE/RETROGRADE CAPTURE ON ASTEROIDS’ SEMIMAJOR AXES

We have investigated the dependence of the prograde/retrograde temporary capture of asteroids by a planet on their original heliocentric semimajor axes through analytical arguments and numerical…

On the Chaotic Orbits of Disk-Star-Planet Systems

Following Tancredi et al.'s criteria of chaos, two ways of setting initial velocities are used in numerical surveys to explore possible chaotic and regular orbits for disk-star-planet systems. We…

Irregular satellites of Jupiter: capture configurations of binary-asteroids

The origins of irregular satellites of the giant planets are an important piece of the giant “puzzle” that is the theory of Solar System formation. It is well established that they are not in situ…

Irregular Satellites of the Planets: Products of Capture in the Early Solar System

All four giant planets in the Solar system possess irregular satellites, characterized by large, highly eccentric and/or inclined orbits that are distinct from the nearly circular, uninclined orbits…

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 stability…

Nebular Gas Drag and Planetary Accretion

Abstract We have studied the orbital dynamics of planetesimals whose decay due to gas drag in the primordial solar nebula causes them to spiral sunward and approach a growing planet. The planet is…

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.

Time analysis for temporary gravitational capture - Stable orbits

In a previous work, Vieira Neto & Winter (2001) numerically explored the capture times of particles as temporary satellites of Uranus. The study was made in the framework of the spatial, circular,…

The Orbits of the Retrograde Jovian Satellites

Abstract The orbits of Jupiter's four retrograde satellites are strongly perturbed by the Sun and therefore resist treatment by the perturbative methods of classical celestial mechanics. We have…

Formation of Kuiper-belt binaries by dynamical friction and three-body encounters

It is shown that a transient binary forms when two large bodies penetrate one another's Hill sphere (the region where their mutual forces are larger than the tidal force of the Sun) and the loss of energy needed to stabilize the binary orbit can occur through dynamical friction from surrounding small bodies, or through the gravitational scattering of a third large body.

Abstract We have studied the capture of planetesimals in Trojan orbits by a growing proto-Jupiter by integrating numerically the equations of motion of planetesimals in a four-body problem…
