Hum,
recent discoveries and computer simulations on the effect of smaller `broken-up asteroidlets` show that they can be far more devastating than a single impact.
Multiple airbursts would create a superheated shock blast that would incinerate hundreds or thousands of square kilometres.
Nuking an asteroid may be the worst thing to do.
See `Libyan glass` or `Kebira Crater`

This week the Space Foundation debuted "Asteroid Challenge, Target: Earth," a virtual lab and video science education program featuring the real asteroid Apophis. Third grade students from Manitou Springs Elementary School in Colorado were the first class nationwide to participate in this interactive science program and use scientific methods in a virtual lab to save our planet from destruction by Apophis, now on a path that could bring it dangerously close to colliding with Earth in 2036.
The release of the lab follows the Oct. 3 premiere of NOVA scienceNow on PBS, which also addressed near-Earth asteroids, including Apophis. Dr. Neil deGrasse Tyson is both the host of NOVA scienceNow and featured in "Asteroid Challenge, Target: Earth." Tyson is a Space Foundation board member, astrophysicist, and director of the Hayden Planetarium in the Rose Centre for Earth and Space at the American Museum of Natural History in New York City.
