Most comets originate from this broad region past the orbit of Neptune reaching farther than 55 AU from the Sun. Oort Cloud - it is theorized that our solar system is surrounded by debris at the gravitational extent of our solar system. The oort cloud is rumored to be 50,000 AU to a light year in distance, making it of the distance to the nearest star, Alpha Centauri.
