Late Heavy Bombardment
The Late Heavy Bombardment refers to a period approximately 4.1 to 3.8 billion years ago during which the inner solar system experienced a high rate of asteroid and comet impacts. This event is believed to have played a significant role in shaping the surfaces of rocky planets like Earth, causing widespread cratering and potentially influencing the development of early life. The Late Heavy Bombardment is thought to have ended as the solar system settled into a more stable state.
