486958 Arrokoth in the Kuiper Belt, previously called 2014 MU69 and nicknamed "Ultima Thule" was the farthest object in the solar system visited by a spacecraft when NASA's New Horizons conducted a ...

CAMBRIDGE, Mass. — Until now, astronomers have used telescopes to find Kuiper Belt objects (KBOs), moon-sized bodies, and obtain their spectra to determine what types of ices are on their surface.

Astronomers at Princeton University have uncovered evidence that the outer solar system is more structured than long believed ...

Far beyond Neptune, astronomers have finally confirmed a compact clump of icy worlds hiding inside the Kuiper Belt, a feature ...

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.

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 trans-Neptunian region, extending beyond Neptune, represents a primordial reservoir of icy and rocky bodies that have remained relatively unchanged since the Solar System’s formation. Central to ...

Fresh mapping of the outer solar system has revealed a previously unseen pattern in the Kuiper Belt, the icy ring of debris beyond Neptune that has long been treated as a relatively simple torus of ...

The Solar system is bigger than NASA thought. There are a lot of huge objects at the edge of the solar system that we have not seen but can indirectly estimate. When astronomers say Kuiper Belt Object ...

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 ...

There may be a warp in the Kuiper Belt, possibly caused by “Planet Y” — a Mercury-to-Earth-sized world that orbits the sun way beyond the orbit of Neptune. Is there a mysterious “Planet Y” orbiting ...
