The Late Heavy Bombardment (LHB) is a theory that the Earth, and the entire inner solar system, suffered through an intense spike in asteroid bombardment roughly 4 billion years ago.

In which era did meteorites bombardment Earth?

The Late Heavy Bombardment (LHB), or lunar cataclysm, is a hypothesized event thought to have occurred approximately 4.1 to 3.8 billion years (Ga) ago, at a time corresponding to the Neohadean and Eoarchean eras on Earth.

What is the early bombardment period?

Since the rate of collision between bodies was high during this time, many scientists refer to this period as either the early bombardment period or the early heavy bombardment period. This period of early heavy bombardment is believed to have taken about the first 0.5 billion years of solar system history.
