That&#8217;s about 900 light-seconds. Still, this deep exposure captures the comet from another star system as it gently swept across a faint background of stars in the constellation Leo about 4 days earlier, on the night of December 15. Though faint, colors emphasized in the image data, show off the comet&#8217;s yellowish dust tail and bluish ion tail along with a greenish tinged coma. And even while scrutinized by arrays of telescopes and spacecraft from planet Earth, 3I ATLAS is headed out of the Solar System. It&#8217;s presently moving outward along a hyperbolic trajectory at about 64 kilometers per second relative to the Sun, too fast to be bound the Sun&#8217;s gravity. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap251226.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Attention grabbing interstellar visitor 3I\/ATLAS made its not-so-close flyby of our fair planet on December 19 at a distance of 1.8 astronomical units.
