An Oort Cloud is a very expansive spherical shell, located in the far system, around most stars or star systems, consisting of numerous small bodies of cometary material.

Description (Specifications)[edit]

A typical Oort cloud lies between 0.5 and 1 light-years from its primary star and has an aggregate mass generally equivalent to that of Terra, a large world; density is thus extremely low.

History & Background (Dossier)[edit]

The Oort cloud is named after its discoverer, Terran astronomer Jan Oort.

Cometary Bodies[edit]

The main constituents of cometary bodies are ice and dust ("dirty snowballs").

Cometary Collisions[edit]

Bodies in the Oort cloud are occasionally perturbed by collisions or by the influence of nearby stars into orbits which pass near the star; these form the visible comets.
