网页More than 1,300 KBOs have been iden-tified since 1992. They are sometimes called Edgeworth–Kuiper Belt objects or transneptunian objects — TNOs for short. The Kuiper Belt should not be confused with the Oort Cloud, which is a thousand times more distant.
In Depth | Kuiper Belt – NASA Solar System Exploration
网页The 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 …

New Horizons Successfully Explores Ultima Thule
网页2019年1月1日 · NASA's New Horizons spacecraft flew past Ultima Thule in the early hours of New Year's Day, ushering in the era of exploration from the enigmatic Kuiper Belt, a region of primordial objects that holds keys to understanding the origins of the solar system.
New Horizons Spacecraft Homing in on Kuiper Belt Target
网页2018年12月31日 · After 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.
Hubble to Conduct Largest-Ever Survey of Kuiper Belt
网页2019年4月2日 · At the present time, the properties of the Kuiper Belt’s unique population of binary systems can only be accurately measured with Hubble. SwRI leads this large HST project focused on characterizing the binary and color properties of over 200 unique KBOs.
In Depth | Our Solar System – NASA Solar System Exploration
网页Our solar system extends much farther than the eight planets that orbit the Sun. The solar system also includes the Kuiper Belt that lies past Neptune's orbit. This is a sparsely occupied ring of icy bodies, almost all smaller than the most popular Kuiper Belt Object – dwarf planet Pluto.
In Depth | Triton – NASA Solar System Exploration
网页Scientists think Triton is a Kuiper Belt Object captured by Neptune's gravity millions of years ago. It shares many similarities with Pluto, the best known world of the Kuiper Belt. Like our own moon, Triton is locked in synchronous rotation with …
