NASA has released new images of 3I/Atlas, the comet that came from another solar system and will get closest to Earth on December 19. The comet could be anywhere from 1,444 feet across to 3.5 miles across, is moving exceptionally fast and is the third interstellar object to enter our solar system. Many questions have been raised about 3I/Atlas. Vlad Duthiers does a deeper dive into what we know about the comet – which is visible from Earth. #nasa #spac #comet #3iatlas | CBS News
