A Survey for Outer Satellites of Mars: Limits to Completeness

We have surveyed the Hill sphere of Mars for irregular satellites. Our search covered nearly the entire Hill sphere, but scattered light from Mars excluded the inner few arcminutes where the satellites Phobos and Deimos reside. No new satellites were found to an apparent limiting red magnitude of 23.5, which corresponds to radii of about 0.09 km using an albedo of 0.07.

A survey for satellites of Venus
Abstract We present a systematic survey for satellites of Venus using the Baade–Magellan 6.5 m telescope and IMACS wide-field CCD imager at Las Campanas observatory in Chile. In the outer portions of
Satellite searches at Pluto and Mars
Abstract We report the results of searches for outer satellites of Pluto and Mars, carried out with the Hale 5-m telescope in 1999 and 2001, respectively. No new satellites were found down to
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
Irregular Satellites of the Giant Planets
The irregular satellites of the outer planets, whose population now numbers over 100, are likely to have been captured from heliocentric orbit during the early period of solar system history. They
A deep search for Martian dust rings and inner moons using the Hubble Space Telescope
Abstract It has long been suspected that Mars might be encircled by two faint rings, one originating from each of its moons Phobos and Deimos. Meteoroid impacts into these moons should release clouds
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 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
Moon search algorithms for NASA's Dawn Mission to asteroid Vesta
The objectives of this paper are to introduce the natural satellite search problem, present the computational challenges, approaches, and tools used when addressing this problem, and describe applications of various image processing and computational algorithms for performing satellite searches to the electronic imaging and computer science community.


Mars: Satellite and ring search from viking
Abstract A search for satellites and rings of Mars was made in 1980 using imaging data taken from the Viking Orbiter 1 spacecraft. A region inside of the orbit of Phobos and ±350 km about the Mars
The dust belts of Mars.
From the unrelated facts that Mars is subjected to a flux of asteroidal projectiles and that it has two very small satellites, an elementary analysis leads to the proposition that the planet
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.
Solar Tidal Friction and Satellite Loss
This paper treats the dynamical evolution of a satellite orbiting a primary that is being despun by solar tidal friction. The results are then applled to Mercury and Venus. It is concluded that a
Where are the Satellites of the Inner Planets
AMONG the more perplexing features of the Solar System's morphology is the scarcity of satellites in the inner Solar System: neither Mercury nor Venus seems to have satellites, the Earth has only
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.
The Discovery of Uranus XIX, XX, and XXI
Abstract Motivated by the discovery of the first two irregular satellites of Uranus in 1997, our team has conducted a search covering approximately 90% of the dynamically stable region around Uranus.
Origin and evolution of the natural satellites

On the formation of the outer satellite groups of Jupiter
Abstract This paper presents evidence suggesting that Jupiter's seven outer satellites, which exist in two distinct groups, were formed by a single collision of an asteroid and a larger satellite.
Dynamics of binary asteroids: II. Jovian perturbations
Abstract The orbital evolution of binary asteroids is controlled mainly by the perturbing attraction of the Sun, although over the long run the smaller effect brought about by Jupiter may cause
