The Kuiper belt, a disc of icy rocks on the outermost edges of the solar system, seems to have more structure than we thought. In 2011, researchers found a cluster of objects there on similar orbits ...

Since the 1990s, astronomers have found a handful of other dwarf planets in the belt, such as Eris and Sedna, along with ...

Astronomers have spotted an intriguing cluster of objects in the Kuiper belt, the enormous, donut-shaped region of icy objects beyond the orbit of Neptune. This latest “inner kernel” was identified by ...

The Kuiper Belt has long fascinated astronomers, not only because it sits at the edge of our Solar System, but because it preserves some of the earliest material that formed around the Sun. For years, ...

If you travel far enough away from the Sun, the Solar System becomes a lot more populated. Out past the orbit of Neptune lies the Kuiper Belt, a vast, ring-shaped field of icy rocks. This is where ...

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 ...

This artist's concept depicts one of the possible scenarios for the 148780 Altjira system in the solar system's Kuiper Belt. It is likely a hierarchical triple formation, in which two very close ...

Astronomers at Princeton University have uncovered evidence that the outer solar system is more structured than long believed. Led by astrophysics doctoral student Amir Siraj, the research points to a ...
