The large asteroid that hit Earth and caused the extinction of the dinosaurs 66 million years ago "was not alone", researchers have confirmed.
The BBC has written that a second space rock, smaller than the first, had crashed off the coast of West Africa creating a large crater during the same era.
Scientists from Heriot-Watt University have said it is believed to have been a "catastrophic event", causing a tsunami about 800 meters high across the Atlantic Ocean.
Researcher Wisdean Nicholson has said that in 2022 the Nadir crater was first discovered, and now he said it has been confirmed that the massive asteroid crashed into the seabed.
They can't quite pinpoint the event, but it was said to have pushed back the "reign of the dinosaurs" and the second falling asteroid collided and created a fireball.
"Imagine that the asteroid was hitting the city of Glasgow (in Scotland) and you are in Edinburgh (Great Britain), about 50 kilometers away. The fireball would be about 24 times the size of the sun - enough to set trees and plants in Edinburgh on fire," researcher Nicholson said.
The asteroid that created the Nadir crater was about 500 meters across and scientists think it hit Earth at about 72.000 kilometers per hour. Asteroid Nadir was the size of asteroid Bennu, currently considered the most dangerous object orbiting near Earth.
According to NASA, September 24, 2182 is the most likely date for Bennu to hit Earth, although the probability is 1 in 2700.
There has never been an asteroid impact of this size in human history.
