Asteroid Day 2022: 7 massive craters on Earth visible from space



Those rogue space rocks have their own holiday: International Asteroid Day, celebrated on June 30.

It’s held on the anniversary of the Tunguska explosion, when part of an asteroid fell to Earth and disintegrated in a massive fireball over Siberia in 1908.

Beyond Siberia, our planet bears many scars from past impacts, some so massive that they’re visible from space.

They serve as a reminder of how powerful — and common — falling asteroids can be.

Here are 7 impressive impact craters around the globe:
