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.

A new study led by Southwest Research Institute (SwRI) Planetary Scientist and Associate Vice President Dr. Alan Stern posits that the large, approximately 5-kilometer-long mounds that dominate the ...

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 ...

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 ...

The farthest object ever explored is slowly revealing its secrets, as scientists piece together the puzzles of Ultima Thule — the Kuiper Belt object NASA’s New Horizons spacecraft flew past on New ...

Pluto, considered the ninth planet in our solar system until it was reclassified to dwarf planet status in 2006, is thought to have undergone an impact that broke off the largest of its five moons, ...
