Scientists have finally pinpointed the origin of the asteroid that killed the dinosaurs, and it’s a fascinating story. The asteroid, known as the Chicxulub impactor, is believed to have formed beyond Jupiter’s orbit, making it a rare and cosmic event. This discovery was made possible by analyzing sediment samples from the time of the asteroid’s impact and measuring the isotopes of the element ruthenium, which is rare on Earth but common on asteroids.
The study, published in the journal Science, reveals that the asteroid was a C-type asteroid, which formed in the outer solar system. This discovery is significant because it can help us better understand the origin of water on Earth and prepare for potential future threats.
The researchers used an innovative technique to analyze the sediment samples, which were formed at the time of the asteroid’s impact. By measuring the isotopes of ruthenium, they were able to determine that the asteroid formed beyond Jupiter’s orbit. This discovery is a major breakthrough in understanding the origin of the asteroid that killed the dinosaurs.
The study also ruled out the possibility that the asteroid was a comet, which was previously suggested in a 2021 study. Instead, the asteroid is believed to be a C-type asteroid, which formed in the outer solar system.
This discovery is significant because it can help us better understand the origin of water on Earth. Scientists believe that water may have been brought to Earth by asteroids, likely of the C-type like the one that struck 66 million years ago. By studying the origin of the asteroid, we can gain a better understanding of how water arrived on our planet.
Furthermore, this discovery can help us prepare for potential future threats from asteroids. By understanding the origin and composition of asteroids, we can better identify potential threats and take steps to prevent them.
