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

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 ...

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

There are eight official planets (sorry, Pluto) in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and ...

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.

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 ...

Among the finds is an object thought to be an asteroid from the main belt, which lies between the orbits of Mars and Jupiter.

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 ...

Until now, the thinking was that Pluto and Charon formed like Earth and our Moon. New research has flipped that script.
