Browsing: Ultima Thule

Ultima Thule, officially designated as 486958 Arrokoth, is a trans-Neptunian object located in the Kuiper Belt, a region of the solar system beyond the orbit of Neptune. It gained significant attention when NASA’s New Horizons spacecraft performed a flyby on January 1, 2019, making it the most distant object ever visited by a spacecraft. Ultima Thule is a contact binary, meaning it consists of two lobes that are in direct contact with each other, resembling a snowman. The larger lobe is named “Ultima” and the smaller lobe is named “Thule.” This ancient object, formed about 4.5 billion years ago, provides scientists with valuable insights into the early solar system’s conditions and processes. The data collected by New Horizons revealed details about its composition, geology, and the way small planetary bodies evolve over time, enhancing our understanding of the primordial materials that make up our solar system.
