New Study Traces Dinosaur-Killing Asteroid's Origin to Outer Solar System

Researchers identify rare element ruthenium in crater samples, suggesting asteroid came from beyond Jupiter's orbit.

Scientists analyzed ruthenium in Chicxulub crater samples, linking the asteroid to the outer solar system.
The asteroid's impact caused mass extinction, wiping out 75% of Earth's species, including most dinosaurs.
The Chicxulub impactor was likely a carbonaceous chondrite, a clay-rich asteroid type.
Jupiter's early movements may have nudged the asteroid toward Earth.
Findings help understand the dynamic nature of our solar system and potential future asteroid threats.
