A college student seems to have cracked the code as to how snowman-like objects floating at the outer edges of the solar system<\/a> are formed.<\/p>\n Jackson Barnes, a graduate student at Michigan State University, created a simulation that reproduces the objects “naturally with gravitational collapse,” MSU Today<\/a> shared on Monday, Feb. 16.<\/p>\n “We\u2019re able to test this hypothesis for the first time in a legitimate way,” Barnes said. “That\u2019s what\u2019s so exciting about this paper.”<\/p>\n The paper was published in the Monthly Notices of the Royal Astronomical Society – Oxford University Press for March by authors Barnes, Stephen Schwartz, from the Planetary Science Institute of Tucson, Arizona, and Seth Jacobson, of MSU.<\/p>\n \u201cGravitational collapse fits nicely with what we\u2019ve observed,” Jacobson, an Earth and Environmental Science Assistant Professor, told the college outlet.<\/p>\n NASA<\/a> first discovered these objects, called Arrokoth, in 2014, and has debated their origins since. However, a YouTube video of Barnes’ simulation shows two objects becoming “contact binaries” and joining together to create the resemblance of a snowman.<\/p>\n \u201cIf we think 10% of planetesimal objects are contact binaries, the process that forms them can\u2019t be rare,\u201d\u00a0Jacobson added to MSU Today.<\/p>\n The Arrokoth objects were found by NASA’s New Horizons spacecraft’s science team with the Hubble Space Telescope. Then, in 2019, the space organization conducted a high-speed flyby to explore the Arrokoth.<\/p>\n “The strange shape of\u00a0Arrokoth, unlike any object previously visited, was the biggest surprise of the New Horizons spacecraft\u2019s flyby,” according to NASA’s page about Arrokoth<\/a>.<\/p>\n They are located in the Kuiper Belt, a region on the solar system’s outer edge that includes Pluto, comets and other small planets made of dust and ice, according to the Detroit Free Press<\/a>.<\/p>\n
