The Kuiper Belt is a ring of icy worlds beyond Neptune

Past Neptune lies the Kuiper Belt — a vast doughnut of icy leftovers including Pluto and countless smaller bodies that never became full planets.

Short-period comets often start here before sunlight wakes their tails. The belt is a deep-freeze archive of the solar system’s building materials.

Looking outward past the giants reveals a second asteroid-like zone made of ice. The solar system does not end at Neptune; it frays into a cold swarm.
