Oort Cloud (Astrography) Synopsis
A spherical shell around most stars, containing numerous small bodies of cometary material.
A typical Oort cloud is about 0.5 to 1 light year from its primary and has an aggregate mass about that of Earth; density is thus extremely low.
Oort Cloud (Astrography) Origin
The Oort cloud is named after its discoverer, Terran astronomer Jan Oort.
Oort Cloud (Astrography) Cometary Bodies
The main constituents of cometary bodies are ice and dust ("dirty snowballs").
Oort Cloud (Astrography) Cometary Colliions
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.
