There are not one, but three potential boundaries to the solar system, according to NASA: the Kuiper Belt, the ring of rocky bodies beyond the orbit of Neptune; the heliopause, the edge of the sun's magnetic field; and the Oort Cloud, a distant reservoir of comets that are barely visible from Earth.
