A small asteroid is expected to make a close approach to Earth today, 7 July, according to NASA. While the object poses no immediate danger, space agencies around the world are monitoring its path closely.
The asteroid, officially named 2025 NJ, is estimated to be around 65 feet (20 metres) wide, roughly the size of a light aircraft. Travelling at an astonishing speed of 30,329 miles per hour (48,800 km/h), it will pass Earth at a distance of approximately 2.24 million kilometres. Though this may seem far, astronomers consider it a near-Earth encounter.
NASA has confirmed that the asteroid does not pose any threat to the planet. An object is only considered potentially hazardous if it is larger than 85 metres and comes within 7.4 million kilometres of Earth thresholds 2025 NJ does not meet.
Nevertheless, scientists continue to track its movement. Even a small shift in its orbit could affect future flybys. 2025 NJ belongs to the Aten group of asteroids, known for orbits that frequently cross Earth’s path. These near-Earth objects are a key focus for researchers working on planetary defences.
While today’s encounter will pass without incident, the Indian Space Research Organisation (ISRO) is looking ahead to more significant threats. ISRO Chairman S. Somanath has underlined the importance of preparing for the future, pointing to asteroid Apophis, which is expected to pass close to Earth in 2029.
ISRO is seeking collaboration with international space agencies including NASA, the European Space Agency (ESA), and Japan’s JAXA to improve tracking systems and develop deflection technologies. The agency also plans to launch missions to land on asteroids, aiming to better understand their structure and test possible defence strategies.
