Marcus - 4/1/2007 2:00 PMAttach rockets to it and nudge it's orbit into an Earth-capture trajectory, then mine the bejeezus out of it!Oh, but please make sure that's a gravitational capture and not a lithosphere capture.

HD209458 - 10/1/2007 1:48 PMSo what if instead you went up and buried several nuclear bombs some fraction of the way along the velocity axis of 2006 XG1? Then you would set the bombs off, and cleave a large section of the asteroid off, effectively using it as your propellant mass.
There are a number of asteroids with much lower C3 at approach than 2006 XG1. Here's some data from the JPL site taken and sorted by C3. The V-infinity (which is the square root of C3) is the last column.
