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

Scientists propose Pluto and its moon Charon formed through a "kiss and capture" event 4.5 billion years ago, challenging previous theories about their unique size ratio and orbital relationship.

Pluto and its largest moon Charon could have come together via a 10-hour “kiss-and-capture” encounter after a grazing collision
