Comets, the Kuiper Belt, and the Oort Cloud

Lecture no. 18 from the course: A Field Guide to the Planets

Comets, the Kuiper Belt, and the Oort Cloud

Taught by Professor Sabine Stanley | 32 min | Categories: The Great Courses Plus Online Science Course

Learn why scientists believe comets—the “leftovers” of planet formation in the outer solar system—could be partially responsible for the flourishing of life on Earth, bringing both water and organic material to the inner solar system. And explore the more distant Oort Cloud, where billions of cometary objects orbit at the outermost boundary of the solar system.
