The outer solar system
The outer solar system extends beyond a heliocentric distance of 5AU. It contains the giant planets and their systems (rings and satellites), the Kuiper belt, the comets (except those which approach episodically the inner solar system) and, at its outer edge, the Oort cloud. The outer solar system physically corresponds to the region located outside the « snow line » which corresponded to the d...
متن کامل4.2.4 Planets of the outer Solar System
The planets of the outer Solar System are Jupiter, Saturn, Uranus and Neptune. The former two are the giant planets, the latter two are also known as sub-giants. The planets are significantly more massive (compare Table 1 of Section 4.2.2.2) than the terrestrial planets and have considerably larger radii. Their mean densities are much smaller, between roughly 690 kg/m (Saturn) and 1640 kg/m (Ne...
متن کاملProbing small bodies in the outer solar system with stellar occultations
We present a summary of results from the last decade of stellar occultation studies by members of the MITWilliams consortium. Research goals included investigations of the atmospheres and figures of small bodies in the outer solar system, focusing on Triton, Pluto, and Charon. We concentrated on the prediction, observation, and analysis of stellar occultations by these bodies. The method of obs...
متن کاملConstraints on an Outer Solar System Late Heavy Bombardment from Callisto’s Interior
Introduction: One difficulty in explaining the lunar late heavy bombardment (LHB) lies in identifying a source of impactors that survives at ~3.8 to 4 Gyr, so long after planet formation [1,2]. A leading theory is that the LHB was triggered by events in the outer solar system [3,4]. Any model that invokes an outer solar system source for the lunar LHB will also produce an intense bombardment on...
متن کاملNomenclature in the Outer Solar System
We define a nomenclature for the dynamical classification of objects in the outer solar system, mostly targeted at the Kuiper belt. We classify all 584 reasonable-quality orbits, as of May 2006. Our nomenclature uses moderate (10 m.y.) numerical integrations to help classify the current dynamical state of Kuiper belt objects as resonant or nonresonant, with the latter class then being subdivide...
