The Kuiper Belt extends from about 30 to 55 AU and is prob-ably populated with hundreds of thousands of icy bodies larger than 100 kilometers (62 miles) across and an estimated trillion or more comets.
- In Depth | Eris – NASA Solar System ExplorationDwarf planet Eris is a member of a group of objects that orbit in a disc-like zone beyond the orbit of Neptune called the Kuiper Belt. This distant realm is populated with thousands of miniature icy worlds, which formed early in the history of our solar system about 4.5 billion years ago.

This distant realm is populated with thousands of miniature icy worlds which formed early in the history of our solar system about 4.5 billion years ago.
- New Horizons Spacecraft Homing in on Kuiper Belt TargetAfter a 13-year journey, the piano-sized spacecraft has covered a distance of four billion miles to reach Ultima Thule in the Kuiper Belt — a donut-shaped region of ancient, rocky bodies beyond the orbit of Neptune.
- In Depth | Kuiper Belt – NASA Solar System ExplorationThe Kuiper Belt represents an enormous, donut-shaped volume of space in the outer solar system. While there are many icy bodies in this region that we broadly refer to as Kuiper Belt Objects (KBOs) or trans-Neptunian objects (TNOs), they're fairly diverse in size, shape, and color.
