Asteroid Impacts Are More Common Than We Thought

Chelyabinsk Meteoroid Airburst Event Yields Crucial Data

"A team of NASA and international scientists for the first time have gathered a detailed understanding of the effects on Earth from a small asteroid impact. The unprecedented data obtained as the result of the airburst of a meteoroid over the Russian city of Chelyabinsk on Feb. 15, has revolutionized scientists' understanding of this natural phenomenon."

New research shows events like Russian asteroid may happen more frequently

"Existing models predict events like the Chelyabinsk asteroid might hit every 120 or 150 years, but our data shows the frequency may be closer to every 30 or 40 years," explains Brown, the Canada Research Chair in Meteor Science, who also serves as CPSX Director. "That's a big surprise. When Chelyabinsk happened, I would have never expected to see an event big enough to cause damage on the ground. It's totally outside the realm of what we thought likely in our lifetimes based on earlier statistics. Our statistics now suggest this type of event likely happens with more frequency."
