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 کاملThe Horseshoe Crab, Limulus polyphemus: 200 Million Years of Existence, 100 Years of Study
Management of the horseshoe crab, Limulus polyphemus, is currently surrounded by controversy. The species is considered a multiple-use resource, as it plays an important role as bait in a commercial fishery, as a source of an important biomedical product, as an important food source for multiple species of migratory shorebirds, as well as in several other minor, but important, uses. Concern has...
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...
متن کاملAccretion in the Early Outer Solar System
We describe calculations of the evolution of an ensemble of small planetesimals in the outer solar system. In a solar nebula with a mass of several times the Minimum Mass Solar Nebula, objects with radii of 100–1000 km can form on timescales of 10–100 Myr. Model luminosity functions derived from these calculations agree with current observations of bodies beyond the orbit of Neptune (Kuiper Bel...
متن کاملChasing Shadows in the Outer Solar System
The characteristics of the populations of objects that inhabit the outer solar system carry the fingerprint of the processes that governed the formation and evolution of the solar system. Occultation surveys push the limit of observation into the very small and distant outer solar system objects, allowing us to set constraints on the structure of the Kuiper belt, Scattered disk and Sedna popula...
