Asteroids the size of cities, like the one that wiped out the dinosaurs, slammed into the ancient Earth way more often than previously thought, a new study has found.
Approximately every 15 million years, our evolving planet would get a hit by a piece of rock about the size of a city, or even a bigger province, scientists with the new study said in a statement . The research was presented at the Goldschmidt geochemistry conference last week.

Some 66 million years ago, on the Yucatán peninsula in Mexico, a 12 kilometer-wide (7.5 mile-wide) asteroid crashes to Earth. The impact causes an explosion whose magnitude is hard to imagine today: several billion times more powerful than the atomic bomb dropped on Hiroshima.

KNOXVILLE, Tenn. (WVLT) - One of NASA's most audacious missions sounds like it's from the movie 'Armageddon.' A spacecraft heading back to Earth after landing – and then digging – on an asteroid.
"Planetary defense is an aspect that we will learn from this mission," NASA's Dr. Jason Dworkin said.

Among the latter, the most emblematic: the dinosaurs. But how were the dinosaurs faring before this cataclysm? This is the question we try to answer in our new study, the results of which have just been published in the scientific journal Nature Communications .

When the first spacecraft to journey outside the Solar System were built, NASA included plaques in case aliens ever found them. For the Voyager missions, these were upgraded to golden records , subsequently the inspiration for many memes .
Chinese Researchers Consider Rockets to Defend Against Asteroids
Chinese researchers say they believe a group of rockets could be used to change the path of asteroids that might pass near Earth.
A team at China's National Space Science Center carried out simulations on the proposed asteroid defense system.
