Pluto, Charon

Pluto and Charon formed through a 'kiss and capture' collision
New study reveals Pluto and Charon’s origin: a unique "kiss and capture" collision redefines how binary systems form.
A Novel 'Kiss and Capture' Event Gave Pluto Its Largest Moon, Charon, New Study Suggests
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 to be.
How did Pluto’s large moon Charon form? With a ‘kiss,’ scientists say
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 may have captured its moon Charon with a brief kiss
Simulations suggest Pluto and its largest moon may have gently stuck together for a few hours before Charon settled into a stable orbit around the dwarf planet
How Pluto captured its largest moon Charon with a 10-hour icy 'kiss'
"We were definitely surprised by the 'kiss' part of kiss-and-capture. There hasn't really been a kind of impact before where the two bodies only temporarily merge before re-separating!"
Pluto May Have Captured Its Biggest Moon After an Ancient Dance and Kiss
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.
Sealed With a Kiss: The Unexpected Origin Story of Pluto and Its Moon Charon
Pluto and Charon may have formed through a “kiss and capture” mechanism, with the two icy bodies colliding and becoming temporarily stuck together, spinning in a cosmic dance before separating into two objects that are forever bound in orbit,
Pluto’s Weirdly Big Moon May Have Come From A ‘Kiss And Capture’
Pluto's big moon Charon may have a different origin story than scientists suspected. New research suggests the two bodies engaged in a celestial kiss and tango.
Pluto may have ‘kissed’ Charon to capture it
New models reveal Pluto and Charon may have spent some of their early history locked together in an embrace after a grazing collision.
“Kiss and Capture:” The Icy Collision That Bound Pluto and Charon Forever
Pluto and Charon's origin story has been rewritten by a recent study, revealing they formed from a unique "kiss and capture" collision that defies traditional scientific theories. This discovery, emphasizing the structural integrity of icy worlds,
"Kiss and capture": New theory explains how Pluto captured its biggest moon
“Because Pluto is rotating rapidly prior to the collision, and because Charon lies mostly outside of their corotation zone, it is able to ‘push’ Charon off, and Charon starts to slowly migrate out,” first author Dr. Adeene Denton, a planetary scientist from the University of Arizona, told The Guardian.
