Asteroids and the Earth

This New York Times ARTICLE talks about the potential for asteroid collisions. This topic was a part of my first novel, "A Glint in Time", and will play a major role in my second upcoming book.

"THE Earth is pockmarked with the evidence of ancient collisions — huge craters blasted into its surface by asteroids or comets. One such object, striking 65 million years ago in the Yucatán in Mexico, is believed by some experts to be linked to the demise of the dinosaurs.

For a decade, NASA has been busy trying to identify what else is headed this way, particularly those potential “civilization killers” of 1 kilometer (.62 miles) or more in diameter that have orbits coming within 30 million miles of the Earth’s — too close for comfort by space standards."
