The Late Heavy Bombardment (abbreviated LHB and also known as the lunar cataclysm) is a hypothetical event thought to have occurred approximately 4.1 to 3.8 billion years (Ga) ago, corresponding to the Neohadean and Eoarchean eras on Earth. During this interval, a disproportionately large number of asteroids apparently collided with the early terrestrial planets in the inner Solar System, including Mercury, Venus, Earth, and Mars.

"A close-up view of our moon detailing the many craters on its surface. The mosaic of 16 frames captures the craters of Copernicus, Kepler, Aristarchus, and Grimaldi, which were created between 3.8 to 4.1 billion years ago from continuous impacts from high-speed asteroids, in a period that is known as the Late Heavy Bombardment. Also seen in the image is the gloomy Ocean of Storms, a huge lunar mare or sea, made up of solidified basalt from volcanic activity that took place after the Late…
