Astronomers Reveal Sudden Explosion of Small Asteroid Over France

For the first time, astronomers have tracked an asteroid from its discovery to its demise. A rock known as 2023 CX1, which was about one meter wide, crashed into Earth's atmosphere over France on February 13, 2023. Telescopes and networks tracked it after it was spotted just seven hours earlier. Scientists found meteorite fragments scattered throughout Normandy as a result of the explosion. The team's analysis reveals that the asteroid held together until it was about 28 kilometers above the ground, at which point it burst into flames, instantly releasing 98% of its energy. Sudden Breakup and tracking According to the research, the sudden airburst of 2023 CX1 was extremely unusual. This common L-chondrite asteroid did not break apart gradually; rather, it held together until it was about 28 km above the ground, at which point it broke under high pressure (approximately 4 million pascals, or about 40× atmospheric pressure). The majority of the energy from the blast was released ...
