A mysterious visitor from beyond our solar system may soon leave a lasting mark on our planet. Harvard physicist Avi Loeb suggests that the interstellar object known as Comet 3I/ATLAS could potentially deposit cosmic debris into Earth's atmosphere. This rare event offers a unique opportunity to study material originating from a distant star system.
The object reached its closest point to our globe on 19 December 2025, passing approximately 269 million kilometres away, making it only the third verified guest from another system. Experts watching its flight state this gap, nearly double the span between the Sun and us, is much too great for significant chunks to strike our world.
