(To a physicist, everything is spherical at the first approximation...) That's 523.6 cu. meters. At a rock density of 2 to 3 metric tons per cu. meter, that's somewhere between 1047.2 and 1570.8 metric tons. As a disaster, it's on a par with dropping a grand piano on a cartoon coyote. It would be a slow approach and MIGHT drop 10 kilos of meteorites, but probably not unless it grazed the atmosphere at the correct angle. However, a 10-meter asteroid is a tiny playground. What if it were a 100-meter asteroid, ten times bigger, and lots of surface (and about 1,000,000 tons). If you accidentally dropped that object on the Earth, you'd have a 250-meter crater and 0.2 MegaTon blast. Too big to play with. A 33-meter asteroid? Airbursts at 14 kilometers and splatters a lot of fast fragments, but no craters. From this I conclude that the 10-meter asteroid grab is a Modest Proposal. Unless, of course, it's an iron...
