Millions of Interstellar Objects from Alpha Centauri May Inhabit Our Solar System

Astrophysicists at Western University in Canada propose that our solar system could be populated by millions of interstellar objects, potentially originating from the Alpha Centauri star system. These findings offer new insights into the dynamics of galactic neighborhoods.

A computer model, detailed in a study published in The Planetary Science Journal on March 6, 2025, estimates that the Oort Cloud may contain roughly one million objects larger than 100 meters in diameter from Alpha Centauri. This suggests a significant exchange of material between star systems.

The model further indicates that approximately 10 meteors from Alpha Centauri, each smaller than 100 micrometers, might enter Earth's atmosphere every year. These tiny meteors pose no threat to our planet. This research enhances our understanding of how star systems are interconnected through the exchange of interstellar materials.
