Sudden blast of asteroid 2023 CX1 over France reveals new impact risk
Asteroid 2023 CX1 fragmented abruptly instead of breaking apart gradually. At a dynamic pressure of 4 MPa, it disintegrated almost instantly, releasing 98% of its total energy in a concentrated region at 28 km (17 miles) altitude. This sudden failure produced a spherical shock wave, unlike the usual cylindrical energy distribution of most fireballs. Calculations…
