Pluto may have got romantic to capture its largest moon, colliding and engaging in a passionate but icy 10 hour kiss with ...

Unlike how scientists believe Earth's moon formed billions of years ago, Pluto and its biggest moon, Charon, didn't have a messy breakup. New computer simulations show the primitive dwarf planet and ...

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

A new study suggests that the origin of Pluto's largest moon was quite different than our own. Here's what you need to know.

While Charon is currently listed as a satellite or moon by the International Astronomical Union (IAU), consideration is being given to it perhaps being classified as a dwarf planet in its own right, ...

University of Arizona researchers have unveiled evidence of romance at the farthest reaches of the solar system: a cosmic ...

Researchers accounted for the previously overlooked structures of the dwarf planet and moon in computer simulations of a ...

Scientists think a small rock discovered near Earth last August was hurled into space by an ancient impact on the lunar surface.

For decades, astronomers have tried to determine how Pluto acquired its unusually large moon Charon, which is about half the size of the dwarf planet. Now, new research suggests that Pluto and Charon ...

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.

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

Recent simulations link the creation of Pluto and its moon Charon to a colossal impact, akin to the Earth-Moon origin, ...
