New Research About Dinosaur Killing Asteroid

The 10 km diameter object seems to have come from the outer solar system beyond Jupiter, unlike the more recent impacting objects. Researchers analyzed the isotopes of ruthenium in the K-T boundary layer at the end of the Cretaceous period to make their determination. Here's a link to the article:
