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.
- It is an astrographic feature.
- It lies beyond the heliosphere and the heliopause.
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.
Image Repository[edit]
An overview of the Terra system, representative of the structure of a star system and the position of the Oort Cloud.
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.
