Asteroid That Wiped Out Dinosaurs Originated Beyond Jupiter, New Study Confirms

A groundbreaking study published in *Science* reveals that the asteroid responsible for the mass extinction event 66 million years ago, which led to the dinosaurs’ demise, originated beyond Jupiter’s orbit. By analyzing sediment samples, researchers confirmed that this impactor was a C-type asteroid, challenging the previous comet hypothesis.

Key Findings:

Sediment Analysis: Researchers analyzed sediment from the Cretaceous-Paleogene boundary using a technique to measure ruthenium isotopes. This confirmed the asteroid’s origin and ruled out the possibility of it being a comet.
Asteroid’s Origin: Lead author Mario Fischer-Godde, a geochemist at the University of Cologne, emphasized that the asteroid likely formed beyond Jupiter, offering new insights into rare asteroid collisions and the origins of Earth’s water.
Advanced Techniques: The study used cutting-edge methods to distinguish C-type asteroids from others, solidifying the theory that the Chicxulub impactor was a C-type asteroid.

Implications:

Future Threats: The findings suggest that if a C-type asteroid were on a collision course with Earth, it could pose a significant threat. Fischer-Godde warns of the potential dangers, urging caution.
This research not only illuminates a critical moment in Earth’s history but also underscores the importance of monitoring celestial threats.
