Interstellar Comet 3I/ATLAS Passes Earth Safely, Experts Allay Toxicity Concerns
Interstellar comet 3I/ATLAS, observed by Hubble on July 21, 2025, passed Earth at a safe distance of 269 million kilometers on December 19. While containing toxic materials like cyanide, experts, including physicist Avi Loeb, state that solar wind and radiation pressure will sweep away gases and small particles. Larger objects are too few and their trajectories too distant to pose a threat, while smaller particles will burn up in the atmosphere.
