According to data collected by the US space agency, the degree of impact from space rocks is increasing – meaning there is an increased chance of a devastating strike.
This is a sharp leap from the number of asteroids that hit the planet when dinosaurs roam the Earth.
Experts believe that at least three times more rocks have hit the Earth today, although most are incredibly small.
Dr. Thomas Gernon, aAssociate Professor of Earth Sciences at the University of Southampton, who participated in the study, explained the increase.
He said, "The Moon is our closest neighbor, so he gets hits from the same asteroid population.
"For this reason, it provides clean effects because it is different from the Earth that is affected by erosion and the tectonics of the plates that break the impact craters.
"We were able to use the samples collected by NASA astronauts during Apollo missions to show some of the craters.
"And we've been able to use this dataset to calibrate a new crater dating technique using measurements made on NASA's board.
He continued: "In the asteroid belt, mounted somewhere between Mars and Jupiter, some of these cosmic rocks sometimes collide.
"The disintegration of one or more asteroids will potentially generate many fragments that over time can be directed to the Earth.
Over time, these stones are bombarded by sunlight and there is a process that re-emits this energy and essentially gives these fragments a small button that can then send them along the Earth's path.
– Looks like a tide; from one asteroid belt comes a lot of material. "
However, Dr. Gernon said it was unlikely that humanity would be destroyed by a devastating strike soon.
"People do not need to worry about this increased flow," he added.
"We say that the big asteroid strikes – more than 1 km – have passed from one every 3-5 million years 90 million years ago, to about 1-2 every million years."
