Astronomers and space agencies worldwide are closely monitoring 3I/ATLAS, a rare interstellar object passing through the Solar System. The object was discovered on 1 July 2025 by the Asteroid Terrestrial‑impact Last Alert System (ATLAS) telescope in Chile.
Though NASA confirms that 3I/ATLAS poses no immediate threat to Earth, its unusual trajectory and behaviour have stirred concerns. Scientists ask what might occur if the object were on a collision course and how the impact could play out.
