Alpha Centauri is a triple-star system, with one of its stars, Proxima Centauri , being the actual closest star to the Sun at 4.25 light-years away.

Researchers from the University of Western Ontario have estimated how many of its space rocks might have reached our corner of the universe.

If the Alpha Centauri system loses as many objects as the Solar System does, then within the Oort cloud, there are about one million interstellar objects larger than 100 meters ( 330 feet ) that have been sent over.
