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

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

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

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 ...

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, ...

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 ...

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 ...

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 ...
