About this listen

Where do comets come from? If their surface material evaporates as they approach the sun, they must have formed far away from the Sun. Comets, along with several icy planetesimals are believed to originate from a theoretical spherical cloud located almost 2 light-years from the sun, called the Oort Cloud. This episode explores this massive structure, the most distant part of our Solar System, and how it came to be.
