How big was the asteroid that killed the dinosaurs?
Answer:
The asteroid that caused the mass extinction of the dinosaurs upon impact is estimated to have been approximately 6 to 9 miles (10 to 15 kilometers) in diameter. This enormous asteroid hit Earth around 66 million years ago in what is now the Yucatan Peninsula in Mexico. The impact is said to have caused devastating effects, leading to a chain reaction of events that ultimately wiped out the dinosaurs and altered the course of evolution on our planet.
