Dinosaur-killing asteroid was likely a giant mudball, study says

Scientist Study Chemical Identity of Asteroid That Caused Dinosaur Extinction #

A new study published in the journal Science reveals that researchers have determined the chemical makeup of the asteroid responsible for the mass extinction event that killed the dinosaurs. The asteroid was a clay-rich mudball that contained materials from the early solar system. This discovery is crucial in understanding the dynamic nature of our Solar System. The impact of the asteroid resulted in a cloud of dust that covered the Earth, blocking out sunlight and causing a drop in temperatures for years. Knowing more about the properties of asteroids is important for future planetary defense operations.
