Amateur astronomers help track asteroid to French impact site
A What happened
On February 13, 2023, asteroid 2023 CX1, weighing 650 kilograms and less than a meter wide, disintegrated over northwestern France. Amateur astronomers, alongside professionals, tracked its descent, providing critical data on its breakup. The asteroid fragmented violently at approximately 28 kilometers altitude, losing 98% of its mass in two stages. This event marked a rare opportunity to study asteroid disintegration, with around a dozen meteorites recovered for analysis. The collaboration between scientists and the public, including contributions from social media, enabled unprecedented observation of the phenomenon. The findings, published in Nature Astronomy, highlight the potential risks associated with such fragmentation, which could cause more damage than gradual disintegration. This incident underscores the importance of tracking small asteroids and understanding their behavior as they enter Earth's atmosphere.

Why it matters

  • Asteroid Fragmentation Observed: Asteroid 2023 CX1's breakup provided insights into atmospheric disintegration.

  • Collaboration with Amateur Astronomers: Public contributions enhanced data collection and observation accuracy.

  • Meteorite Recovery: Around a dozen meteorites were collected for scientific study.

  • Potential Impact Risks: The fragmentation process poses different risks compared to gradual disintegration.
