Granby is a meteorite impact crater in Sweden with an estimated diameter of about 3 kilometers. It formed roughly 470 million years ago, during the Middle Ordovician period, when an extraterrestrial body struck the Earth's surface. The structure is described as relatively well preserved for its age. Granby is of interest to geologists because its form and impact evidence record a collision during the Paleozoic era.
