Astronomers predict bombardment from asteroids and comets in another planetary system

The planetary system around star HR8799 is remarkably similar to our Solar System. A research team led by astronomers from the University of Groningen and SRON Netherlands Institute for Space Research has used this similarity to model the delivery of materials by asteroids, comets and other minor bodies within the system. Their simulation shows that the four gas planets receive material delivered by minor bodies, just like in our Solar System.
