Stolen comets and free-floating objects
Our Solar System may contain alien comets that were stolen from another star flying past 4.5 billion years ago. Far away in a distant cluster of young stars, a similar close encounter might have also sent the inter-stellar visitor “Oumuamua” flying on its way towards us, and there must be many more of these free-floating objects in the Galaxy. These are results of a new study by astrophysicists at the University of Zurich.
