The three known debris fields in our solar system, the asteroid belt, the Kuiper belt and the Oort cloud are populated with an infinitude of bodies ranging in size from a few feet to several miles across.

From time to time these bodies interact either with each other or with one of the major planets in such a way that one of the minor bodies is ejected from the solar system in a gravitational “slingshot” interaction, analogous to that used by NASA to gravitationally assist space probes on their way to distant destinations in our solar system.

Once ejected in such a fashion, that body will never return to the solar system. As an example, the Voyager space probes launched in the 1970s are currently over 10 billion miles away. Over millions or even billions of years, these probes might one
