Summary

Description	English: Ultima Thule used to be 2 separate objects. It likely formed over time as a rotating cloud of small, icy bodies started to combine. Eventually, 2 larger bodies remained & slowly spiraled closer until they touched, forming the bi-lobed object we see today. http://pluto.jhuapl.edu/News-Center/Press-Conferences/index.php?page=2019-03-18
