The rock and ice objects disintegrated in the Earth’s atmosphere, but the iron object did not. ![]() They were also given different trajectory paths that brought them within 6 to 10 miles of the Earth’s surface. The researchers, including co-author Vladimir Pariev, looked at a number of different computer models, testing objects as small as 164 feet across all the way up to 656 feet across, comprised of rock, ice or iron. No injuries were reported, but some 80 million trees over approximately 800 square miles were leveled. ![]() The 1908 blast is generally estimated to have been about 10 megatons. “We argue that the Tunguska event was caused by an iron asteroid body, which passed through the Earth’s atmosphere and continued to the near-solar orbit,” researchers wrote in the study’s abstract. The research, published in Monthly Notices of the Royal Astronomical Society, theorizes that the asteroid caused a shock wave that resulted in nearly 800 square miles in the Siberian forest to be flattened within seconds, but it never actually hit Earth, as it curved away shortly before breaking up, continuing into space. A new study sheds more light on the asteroid, noting it may have never actually hit Earth at all. The Tunguska event, a seismic blast that rocked a remote Siberian forest more than a century ago, is believed to have been caused by a meteor that exploded before it hit the ground.
