How long would it take for Oort objects that are nudged out of their orbit to become comets buzzing or hitting Earth?
Also, if that star system has its own Oort cloud, could some of the objects there have jumped system and become long-term comets?
- kryptiskt 12y agoThe Nature News article says: "Because Scholz’s star is puny and sped by quickly, it would have had a negligible impact on the Oort cloud, Mamajek notes. And any comets that the star might have sent hurtling towards the inner Solar System will not arrive for another few hundred thousand years, says Tremaine." http://www.nature.com/news/star-buzzed-solar-system-during-human-prehistory-1.16958?WT.mc_id=TWT_NatureNews http://www.nature.com/news/star-buzzed-solar-system-during-h...
