All four giant planets in the solar system possess irregular satellites, characterized by large, highly eccentric and/or highly inclined orbits. These bodies were likely captured from heliocentric orbit, probably in association with planet formation itself. Enabled by the use of large-format digital imagers on ground-based telescopes, new observational work has dramatically increased the known populations of irregular satellites, with 74 discoveries in the last few years. A new perspective on… 

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

The Solar System Beyond The Planets

The Kuiper belt contains a vast number of objects in a flattened, ring-like volume beyond the orbit of Neptune. These objects are collisionally processed relics from the accretion disk of the Sun

A new perspective on the irregular satellites of Saturn - I Dynamical and collisional history

The dynamical features of the irregular satellites of the giant planets argue against an in situ formation and are strongly suggestive of a capture origin. Since the last detailed investigations of

A common mass scaling for satellite systems of gaseous planets

It is shown that the overall properties of the satellite systems of Jupiter, Saturn and Uranus arise naturally, and it is suggested that similar processes could limit the largest moons of extrasolar Jupiter-mass planets to Moon-to-Mars size.

The Capture of Satellites by Binary-Planet Encounters : A Computational Analysis of the Cases of Triton , Phobos and Deimos

Conversely to regular satellites, irregular ones have been widely accepted to be foreign bodies originated elsewhere from their present location, that early in the Solar System history were somehow

Discovery of the Closest Saturnian Irregular Moon, S/2019 S 1, and Implications for the Direct/Retrograde Satellite Ratio

We present a tracked orbit for a recently discovered 25th magnitude irregular moon of Saturn, using Canada-France-Hawaii Telescope imaging. Our 2 yr of observational arc on the moon leads to an orbit

New Jupiter Satellites and Moon-Moon Collisions

We report the discovery of 12 new satellites of Jupiter, giving Jupiter 79 known satellites. The new finds are between 23rd-24th mag in the r-band and 1-3 km in diameter assuming dark albedos. Nine

Three-Body Capture of Jupiter's Irregular Satellites and Resonant History of the Galilean Satellites

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.

An abundant population of small irregular satellites around Jupiter

The discovery of 23 new irregular satellites of Jupiter is reported, so increasing the total known population to 32 and showing five distinct satellite groups, each dominated by one relatively large body.

Discovery of two distant irregular moons of Uranus

The systems of satellites and rings surrounding the giant planets in the Solar System have remarkably similar architectures. Closest to each planet are rings with associated moonlets, then larger

Orbital and Collisional Evolution of the Irregular Satellites

The irregular moons of the Jovian planets are a puzzling part of the solar system inventory. Unlike regular satellites, the irregular moons revolve around planets at large distances in tilted and

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.

Effects of Planetary Migration on Natural Satellites of the Outer Planets

Abstract Numerous studies in the past few years have analyzed possible effects of planetary migration on the small bodies of the Solar System (mainly asteroids and KBOs), with the double aim of

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 latter

The formation of Uranus and Neptune in the Jupiter–Saturn region of the Solar System

The results of model calculations are reported that demonstrate that solid cores of the gas-giant planets Jupiter and Saturn will have been gravitationally scattered outwards as Jupiter, and perhaps Saturn, accreted nebular gas.

Rapid Formation of Outer Giant Planets by Disk Instability

The formation mechanism of the ice giant planets is uncertain. A new hypothesis envisions rapid formation of several gaseous protoplanets in a marginally gravitationally unstable protoplanetary disk,

An Ultradeep Survey for Irregular Satellites of Uranus: Limits to Completeness

We present a deep optical survey of Uranus's Hill sphere for small satellites. The 8 m Subaru Telescope was used to survey about 3.5 square degrees with a 50% detection efficiency at limiting red
