Charon, its biggest of five moons, was discovered in 1978 by the U.S. Naval Observatory. At about 750 miles wide, it's half the size of Pluto — extremely large for a moon.

Pluto likely acquired large moon Charon in a “kiss and capture” collision billions of years ago. It may have created a subsurface ocean on the icy dwarf planet.

Pluto and its moon Charon may have been briefly locked together in a cosmic “kiss”, before the dwarf planet released the smaller body and recaptured it in its orbit.

The icy volcanism of Pluto's large moon Charon and a belt of fractures across its surface may have been caused by a subsurface frozen ocean bursting through a thin ice shell.
