Sun and Earth Filter Fragile Space Rocks, Limiting Carbonaceous Meteorites: Study

An international study published in Nature Astronomy indicates that the Sun and Earth's atmosphere selectively filter and destroy fragile, carbonaceous space rocks before they can reach the planet's surface. Researchers analyzed data from nearly 8,500 meteoroid and meteorite events. This data was gathered from 19 fireball observation networks across 39 countries.

The study suggests that carbon-rich meteoroids are highly susceptible to destruction. This destruction occurs due to repeated heating as they pass close to the Sun. Meteoroids formed through tidal disruptions are also particularly fragile and prone to disintegration.

These findings have significant implications for several fields. These fields include astrobiological research, asteroid missions, and theories concerning the origin of water and organic compounds on Earth.
