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 ...

In a study published recently in Nature Geoscience, researchers unveiled a new theory explaining the formation of Charon, Pluto's largest moon. The team from the University of Arizona proposed that ...

For billions of years, Pluto and its largest moon Charon have been facing each other in a mutual tidal lock. Since it’s about half the size of Pluto, the moon and its planet are sometimes referred to ...

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 ...

A NASA spacecraft bound for Pluto has captured its first photo of the dwarf planet's largest moon Charon, a cosmic snapshot snapped from nearly 550 million miles away. The new Charon photo was taken ...

Labroots recently explored Saturn’s sponge-like moon, Hyperion, with its deep craters and non-spherical shape. This moon is an example of how the Universe and the laws of astrophysics work in both ...

LAUREL, MD. — Pluto got the boot from planethood in 2006. But one of the dwarf planet’s moons, Charon, could get an upgrade, thanks to discussions August 14 during the Great Planet Debate Conference ...
