The Solar System does n't end with Neptune. Beyond the route of this distant ice mammoth lies a vast and mysterious realm called the Kuiper Belt — a circumstellar slice filled with icy bodies, dwarf globes, comets, and bones from the Solar System’s conformation. This region, roughly 30 to 55 astronomical units( AU) from the Sun, serves as a depository for early objects that escaped the gravitational clearing by the giant globes.
