I wasn't paying attention - taking a break at a seminar in Orlando where the resort had the NASA channel on as default - so I didn't catch the complete discussion. But the part I listened to suggested that if we have enough warning, just painting parts of an asteroid could deflect its orbit enough to miss the Earth. Solar wind, I guess would be the motivating factor.

All I could think to do would be to hit an incoming asteroid with a nuclear warhead Maedhros May 2015 #3

Just getting close enough to paint it, will probably alter its course. immoderate May 2015 #11

True - I've read that the course can be altered by traveling close csziggy May 2015 #12

Not sure what you would call that. immoderate May 2015 #15

If we can encounter it when it's 100 million miles away (roughly 1 AU, just past Mars) immoderate May 2015 #10
