It has been discovered where the giant asteroid that wiped out the dinosaurs came from

Came from beyond Jupiter

According to researchers, unlike most small asteroids hitting our planet these days, the one that caused the extinction of the dinosaurs was the one that caused the extinction of the dinosaurs. about 10 kilometers wide asteroid, gas giant from beyond Jupiter came. According to the findings, this is a It was a C-type asteroid and came from the dark regions of the outer Solar System. C-type asteroids rich in carbon We know that they are 75 percent of all known asteroids.

The impact of the giant asteroid hitting the Earth was just as great. Today this impact zone Chicxulub Krateri is called and is largely Yucatan peninsulaIt is buried under . The asteroid hit shallow waters, throwing a tremendous amount of debris into the sky and causing sunlight to reach the earth. Therefore, over time, photosynthesis stopped and a long winter took effect. Ultimately, on Earth nearly 70 percent of species became extinct.

According to researchers K-Pg boundary There is a thin layer of sediment left over from this event, called Earth, around our planet. And in this sediment routesum There is an extremely rare element in the Earth’s crust. Scientists say almost 100 percent of the ruthenium in this sediment layer comes from the asteroid.

More importantly, the researchers found that the ruthenium isotopes (which are different types of ruthenium) in this defining layer resemble carbon-rich meteorites found throughout Earth. Moreover, the ruthenium samples did not match debris from other large asteroid impacts from objects formed in the inner Solar System. Ruthenium was not used in previous analyses.
