Where is the Oort Cloud thought to begin?
Quick Answer
The Oort Cloud is thought to begin far beyond the Kuiper Belt, thousands of astronomical units from the Sun.
The Full Story
The Oort Cloud is a hypothetical spherical shell of icy bodies surrounding the Solar System. It is believed to start at distances of perhaps 2,000 astronomical units or more, though its exact inner edge is uncertain. Because no spacecraft has reached it, its existence is inferred from the orbits of long-period comets. It likely extends out to tens of thousands of astronomical units.
Key Facts
1.Likely begins around 2,000 AU or more
2.May extend to tens of thousands of AU
3.Inferred from long-period comets
