AstronomySolar System
Quick Answer
The Oort Cloud is thought to surround the Solar System in a distant spherical shell. It may extend thousands to perhaps 100,000 astronomical units from the Sun.
The Full Story
The Oort Cloud is a theoretical reservoir of icy objects far beyond Neptune and the Kuiper Belt. It is thought to form a vast spherical shell around the Solar System, reaching distances of thousands to perhaps 100,000 astronomical units from the Sun. No spacecraft has visited it, and it has not been directly seen, but it is inferred from long-period comets. It is considered the source region of many comets that enter the inner Solar System.
