What it means
The Oort cloud is inferred rather than seen. Long period comets arrive from every direction rather than along the plane the planets share, which points to a roughly spherical reservoir surrounding the whole system at enormous distance. Its outer parts are so weakly held that a passing star can nudge one of its members onto a path toward the sun.
