The curious minds at What If imagine Earth shrinking to the size of Pluto, exploring how gravity, atmosphere, and life would ...

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 ...

Pluto’s frozen face looks dead at first glance, but its most famous feature hints at something far stranger than a simple ice ...

The “demoted” dwarf planet Pluto and its largest moon Charon make an unusual pair, and for decades, scientists have been discussing how the binary system—in which each mutually orbits the other—came ...

Pluto landed its largest moon, Charon, with a 'kiss'—overturning decades of scientific assumptions about how planetary bodies form and evolve. This is the conclusion of a new study, conducted at the ...

We classified Pluto before really understanding it—just like we reduce people to job titles or put names on relationships ...

New research suggests that billions of years ago, Pluto may have captured its largest moon, Charon, with a very brief icy "kiss." The theory could explain how the dwarf planet (yeah, we wish Pluto was ...

Using advanced models, SwRI led new research that indicates that the formation of Pluto and Charon may parallel that of the Earth-Moon system. In the resulting “kiss-and-capture” regime, Pluto and ...
