It has been reported that city-sized asteroids hit Earth every 15 million years between 3.5 and 2.5 billion years ago.

According to the news of the Daily Mail, in the research conducted by the Southwest Research Institute in the USA, a new modeling study and the earth layer data were analyzed comparatively.

The research revealed that 2.5 to 3.5 billion years ago, Earth was “bombarded” by city-sized asteroids every 15 million years.

It was concluded that these asteroids were significantly larger than the asteroid that destroyed the dinosaurs, while the craters created by the impacts have so far disappeared, but their traces can still be found in spherical glassy particles on Earth.

Physicist Simone Marchi, one of the research team, pointed out that cosmic impacts are a fact that is ignored although everyone knows.

Stating that the lack of detailed information on the number and severity of cosmic impacts caused the issue to be ignored, Marchi said, “These energetic events have probably radically changed the evolution of the Earth’s surface and atmosphere.” made its assessment.

Marchi said that these asteroids, which crashed into the Earth every 15 million years between 3.5 and 2.5 billion years ago, had an impact like the Chicxulub Crater.

Details of the research were presented at the Goldschmidt Geochemistry Conference.
