Comet 3I/ATLAS, an interstellar visitor from beyond the Milky Way, made its closest approach to Earth on December 19, coming within 168 million miles, and is now heading back to the outer solar system. Its trajectory suggests it originated from an older, thick disk region of the galaxy, making it potentially the oldest comet observed. Its unexpected brightening near the sun has intrigued scientists, and data from this encounter will enhance understanding of interstellar objects and galactic history.
