New Study Sheds Light on Mysterious 'Doomsday' Asteroid That Flew Close to Earth A recently published study has provided fresh insights into the trajectory and composition of a small asteroid that made headlines in 2022 for its close approach to Earth. The asteroid, estimated to be around 20 meters in diameter, flew by our planet at a distance of approximately 1,950 kilometers, sparking concerns about potential asteroid impacts. Researchers used advanced tracking data and computer simulations to recreate the asteroid's path and determine its origin, revealing new information about the asteroid's composition and the likelihood of future close calls with Earth. The study's findings have significant implications for asteroid detection and tracking systems, which are crucial for mitigating the risk of asteroid impacts.
