Research Contends Interstellar Asteroids Could Originate From Alpha Centauri

1 million 'interstellar objects' — each larger than the Statue of Liberty — may lurk in the outer solar system

New simulations reveal that around 1 million "macroscopic" objects from our closest stellar neighbors, the Alpha Centauri system, may already reside in the Oort Cloud, far from sight.

Alpha Centauri Sending Stream of Objects Into Our Solar System, Scientists Propose

New research suggests that our Solar System may already be swimming in interstellar objects that originate from the Alpha Centauri system.

Interstellar Asteroids Could Originate From Alpha Centauri, Says Paper

New paper points to the Alpha Centauri triple star system as likely potential source of millions of interstellar asteroids and comets.

Chunks of Alpha Centauri—Our Closest Stellar Neighbor—Might Have Already Reached Us

A new study examines how much material from the closest star system to Earth will end up in orbit around the Sun, and how much could already be here.

Alpha Centauri Particles Already Lurk in Our Solar System, Study Suggests

The appearance of the Interstellar Objects (ISOs) Oumuamua and Comet Borisov in 2017 and 2019, respectively, created a surge of interest.

Material from Alpha Centauri is Already Here

The appearance of the Interstellar Objects (ISOs) Oumuamua and Comet Borisov in 2017 and 2019, respectively, created a surge of interest. What were they? Where did they come from? Unfortunately, they didn’t stick around and wouldn’t cooperate with our efforts to study them in detail. Regardless, they showed us something: Milky Way objects are moving around the galaxy. We don’t know where either ISO came from, but there must be more—far more. How…
