The bringer of a mass extinction
A menacing asteroid, some six miles wide, triggered Earth’s last mass extinction. Now, scientists have found where it originated.
Unlike most space rocks that impact our planet today, this behemoth object came from beyond the gas giant Jupiter. It was a “C-type asteroid” — which are the dark, carbon-rich leftovers of the outer solar system — and the impact scattered the fateful object’s remains all over Earth, some 66 million years ago.
It was “a projectile originating at the outskirts of the solar system and sealing the fate of the dinosaurs,” Mario Fischer-Gödde, who researches the origin of asteroids and planets at the University of Cologne in Germany, told Mashable.
