• Resumen

  • Ashmawi discusses the analysis which has revealed that stars can steal planets from each other in high-speed fly-bys, something that may even have happened in the solar system. Rosalba Pema and her team used computer simulations to investigate what happens when neighbouring stars have a close encounter. They found that fly-bys inside dense clusters of stars wreak havoc on planetary systems, destroying, ejecting or even stealing planets away from their hosts about once every billion years per system.
