A study reveals that there are more asteroids colliding with the Earth than before





A study published recently in the Science magazine reveals that, both our planet and the Moon, are currently receiving nearly three times as many asteroid impacts as 290 million years ago.


This finding contradicts the theory that as the solar system gets older and heavier, the number of asteroids and comets that collide with the planets that inhabit it decreases.


To arrive at this conclusion, the scientists in charge of the investigation examined the surface of the Moon using the data of the Lunar Reconnaissance Orbiter of the POT.





By comparing the craters of the Moon with a chronology of our planet's craters, the researchers also discovered that Earth and the Moon experienced similar stories of asteroid impact.


The Moon is not subject to the same forces, but it does, according to the researchers, to the same bombardment of asteroids and comets.


Therefore, when analyzing the craters have been a surprise: there are more young holes than old, which means that both the satellite and our planet have received more impacts in the last 300 million years.


"Our study provides evidence of a dramatic change, produced towards the end of the Paleozoic era, in the number of asteroid impacts on both Earth and the Moon," said the lead author of the research, Sara Mazrouei, cited by Science Daily.


The theory also includes the idea that one of the collisions in the asteroid belt could cause the asteroid that led to the mass extinction of the dinosaurs. Although, for the moment, this is still just a hypothesis that the researchers raise in this study.
