Scientists say 3I/Atlas came closest to Mars in October. Its path this month put it in the path of the warm rays of our sun, where a tail became more visible. The 3.5-mile solar object is traveling at 137,000 miles per hour, NASA said. Scientists believe it will fly by Earth on or close to Dec. 19. It'll be some 170 million miles away.

I/Atlas isn’t sending messages. We explain the viral clip, the real radio detection from water chemistry, scientist responses, and its safe 170 million mile pass.

I/ATLAS will soon make its closes flyby to Earth. When this happens, Avi Loeb said that all questions could be answered.
