A mysterious interstellar visitor is barreling toward its closest approach to Earth, and the world’s governments are scrambling.
The object, known as 3I/ATLAS, will swing past our planet on Friday at a distance of roughly 170 million miles, and while officials insist there is no imminent danger, the sheer scale of the international response tells a different story.
NASA, the European Space Agency (ESA), and 23 nations have launched a sweeping, year-long planetary defense exercise, the biggest in history.
They are using the object’s arrival to rehearse for the unthinkable: a real, incoming space threat.
