NASA: The "fireball" phenomenon in the Northeastern United States caused by meteor disintegration

NASA confirmed on the 1st that the sonic boom and "fireball" phenomena observed in the New England region of northeastern United States on the afternoon of May 30 were caused by a meteor disintegrating as it entered Earth's atmosphere. The agency posted on social media platform X that around 2 a.m. on May 31 (Beijing time), a meteor approximately 1.6 meters in diameter and weighing about 5.6 tons entered Earth's atmosphere at a speed of about 68k kilometers per hour. The agency stated that after entering the atmosphere, the meteor traveled approximately 42 kilometers from northwest to southeast before disintegrating at an altitude of about 50 kilometers above the ground, with meteor fragments ultimately falling into Cape Cod Bay, Massachusetts. According to the latest calculations, the energy released by the meteor's disintegration was equivalent to an explosion of about 230 tons of TNT, which is also the reason why local residents heard the loud sonic boom.
