Charon is the largest of the five known moons, or natural satellites, of the dwarf planet Pluto. With a diameter of 1,212 kilometres (slightly more than half the diameter of Pluto), Charon is the 12th ...

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. Astronomers zoomed in on a stellar behemoth in the ...

The findings, published earlier this month in the journal Nature Geoscience, challenge the widely accepted notion that Pluto and Charon formed the same way the Earth and moon did, with a ...
