unusually large moon. Since the 1990s, planetary scientists have thought that Charon could have <a href=\"https:\/\/www.sciencenews.org\/article\/impact-formed-moon-earth-mantle\">formed in a similar way to Earth\u2019s moon<\/a>: An impact on the main body splashed hot molten material into orbit, where it eventually coalesced into a large natural satellite.<\/p>\n\n\n\n<p>But, just like with Earth\u2019s moon, <a href=\"https:\/\/www.sciencenews.org\/article\/earth-moon-formation-impact\">the details are fuzzy<\/a>. \u201cIt goes, something hit Pluto, question mark question mark question mark, Charon is now there,\u201d Denton says.<\/p>\n\n\n\n<p>Computer simulations of such collisions seemed to result in a system like Pluto and Charon. But those simulations treated the rocky, icy protoplanets as fluids, ignoring their material strength. That\u2019s a decent assumption for large objects like gas giants or galaxies, which do behave like fluids when something hits them. But Pluto and Charon are ice-wrapped rocks. And it turns out you can\u2019t ignore that.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><p>\n<div class=\"youtube-embed\" data-video_id=\"FozdTaygwJs\"><iframe loading=\"lazy\" title=\"How Pluto met its largest moon Charon | Science News | Science News\" width=\"696\" height=\"392\" src=\"https:\/\/www.youtube.com\/embed\/FozdTaygwJs?feature=oembed&#038;enablejsapi=1\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/p><figcaption class=\"wp-element-caption\">Simulations of Pluto\u2019s and Charon\u2019s first encounter show that each body remained mostly intact after a brief but intense impact. Pluto\u2019s core is shown in blue, Charon\u2019s core is purple. Pluto\u2019s solid ice is shown in yellow, and Charon\u2019s ice is green. The encounter shown here lasts about 60 hours.<\/figcaption><\/figure>\n\n\n\n<p>The real collision would have been a lot less splashy, Denton says. She and her colleagues ran collision simulations that included Pluto\u2019s and Charon\u2019s rocky cores and icy mantles and crusts. The team found that the protoplanets had an instant connection.<\/p>\n\n\n\n<p>The pair joined up and rotated together, but each body remained basically intact. After about 30 hours of contact, Charon separated from Pluto and began to migrate into the orbit it has today.<\/p>\n\n\n\n<p>Denton and colleagues found that two other pairs of objects, dwarf planet <a href=\"https:\/\/www.sciencenews.org\/article\/discordant-name-dwarf-planet\">Eris and its moon Dysnomia<\/a> and dwarf planet Orcus and its moon Vanth, could also be explained by \u201ckiss-and-capture\u201d collisions. She plans to extend the work to other objects with different masses and compositions.<\/p>\n\n\n\n<p>\u201cCan this still work? I\u2019m pretty confident that it does,\u201d she says. \u201cIf that\u2019s true, kiss-and-capture happened all over the Kuiper Belt in the solar system\u2019s history.
