A vast region of our solar system, called the Kuiper belt, stretches from the orbit of Neptune out to 50 or so astronomical units (AU), where an AU is the distance between Earth and the sun. This ...

Astronomer used to think that the Kuiper Belt was a few hundred times larger than the Asteroid belt. They thought it was a donut shaped structure that started at Neptune and extended out 2 billion ...

As next-generation telescopes map this outer frontier, astronomers are bracing for discoveries that could reveal hidden planets, strange structures, and clues to the solar system’s chaotic youth. Out ...

A team of researchers, using data from the W. M. Keck Observatory on Maunakea and NASA’s Hubble Space Telescope, has identified what is likely a rare three-body system in the Kuiper Belt. If confirmed ...

In the outer reaches of the Solar System, beyond the ice giant Neptune, lies a ring of comets and dwarf planets known as the Kuiper Belt. The closest of these objects are billions of kilometers away.

Out beyond the orbit of Neptune lies an expansive ring of ancient relics, dynamical enigmas, and possibly a hidden planet—or two. The Kuiper Belt, a region of frozen debris about 30 to 50 times ...
