They needed some space. New research suggests Pluto may have had a “kiss” with its largest moon billions of years ago in a ...

“Because Pluto is rotating rapidly prior to the collision, and because Charon lies mostly outside of their corotation zone, ...

Pluto and its largest moon Charon could have come together via a 10-hour “kiss-and-capture” encounter after a grazing ...

Within it lies the dwarf planets Pluto, Eris, Orcus and more. It's thought that there exist more than 100,000 Kuiper belt objects over 100 km in diameter. The Cold Classical Kuiper Belt Objects ...

Charon is large in size relative to Pluto, and is locked in a tight orbit with the dwarf planet. A new simulation suggests how it ended up there.

New models reveal Pluto and Charon may have spent some of their early history locked together in an embrace after a grazing ...

Pluto and Charon’s meet-cute may have started with a kiss. New computer simulations of the dwarf planet and its largest moon suggest that the pair got together in a “kiss-and-capture” collision, where ...

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...

A new theory has emerged to explain how Pluto may have captured its largest moon, Charon, billions of years ago through a unique "kiss-and-capture" collision. The process, proposed by researchers, ...

The tantalizing prospect of a ninth planet is suggested by a paper published in The Astronomical Journal, which explores the orbit of objects in the distant Kuiper Belt. The Kuiper Belt (also ...
