Beyond Neptune lies the Kuiper Belt, a vast expanse of icy bodies that may hold clues to the solar system’s formation. These ...

Trans-Neptunian Objects (TNOs) are celestial bodies located in the outer solar system, beyond the orbit of Neptune. This region, known as the Kuiper Belt, is home to a diverse array of icy bodies ...

Pluto likely acquired large moon Charon in a “kiss and capture” collision billions of years ago. It may have created a subsurface ocean on the icy dwarf planet.

Then, a subsequent impact between Charon and a smaller Kuiper Belt object could have produced the debris that formed the system's four small moons: Nix, Styx, Kerberos and Hydra. Learn about the ...

Additionally, 80% of the largest objects in the Kuiper Belt have a large object rotating them like the Pluto-Charon dynamic, and "kiss and capture" events could have occurred in this region in ...

The planet, dubbed Planet Nine, is believed to exist beyond Neptune in the Kuiper Belt. Researchers have noticed unusual gravitational effects on distant objects in this region, which may be ...

"It's a pretty big question since a bunch of other large Kuiper Belt Objects also have large moons, so it seems like this is something that happens in the Kuiper Belt with some frequency ...

"And that has pretty big implications for the Kuiper Belt as a whole, because eight of the 10 largest Kuiper Belt objects are similar to Pluto and Charon.
