Study: Thousands of interstellar objects may reside in solar system's Oort cloud
Research led by Sean Raymond suggests the Sun captured non-native material during close encounters with other stars over 4.6 billion years.
What to know
- A new study models how the Sun likely captured thousands of interstellar objects from other star systems during close encounters with those stars over billions of years.
- These non-native objects are predicted to reside in the Oort cloud, the outermost region of the solar system extending about three light years from the Sun.
- The findings are based on recent confirmed discoveries of interstellar objects passing through the solar system and cannot be directly verified since spacecraft cannot yet reach the Oort cloud.
“Given that flybys are unavoidable in the Galactic field, most stars should host sparse Oort clouds populated with ISOs captured during stellar flybys.”

Our Sun has likely passed so close to other stars in the past that it captured thousands of small interstellar objects from alien systems, according to a new study. https://www. 404media.co/thousands-of-inter stellar-objects-may-be-lurking-in-our-solar-system
