We often discuss our future in the Asteroid Belt, and the glorious civilizations we might one day build there. However, it is ...

“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 harmless collision. The report, published in “Nature ...

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.

Planet X, also called Planet Nine, is a hypothetical planetary body seven times the mass of Earth lurking behind Pluto. If ...

Unlike Earth, where the Moon orbits the planet, Pluto and Charon orbit each other, forming a binary system that is more ...

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 ...

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

The newcomer replacing Pluto presently goes by “Planet Nine.” If and when it finally shows up, it will get the honor of a ...

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 ...
