10. 50,000 years ago, an asteroid slammed into Earth with the strength of 20 million tons of TNT. The result was Meteor Crater, Earth’s best-preserved crater, in northwest Arizona.

9. In 2018, scientists found an impact crater wider than Paris 1,000 feet below the Hiawatha Glacier in Greenland. Scientists think the offending asteroid hit sometime between 12,000 and 3 million years ago with the energy of 45 Hiroshima bombs.
