A Double Meteor Impact Hit Sweden 468 Million Years Ago

In the Swedish county of Jämtland, two large craters mark the site of a rare event: a double meteorite impact. The larger crater of the pair, a few miles south of the city of Östersund, is about 4.7 miles wide. A few miles away lies a smaller crater, nearly half a mile wide. The two craters are the first proven site of a double impact that researchers have identified so far.
