This article interested me because it shows just how helpless we are against potential threats. Dealing with a large asteroid on a collision-course with Earth would likely not involve more than contingency plans after impact. The fact that this asteroid missed Earth is pure luck, which we rely on perpetually in regard to asteroid strikes. It is fascinating how easy it is for humans to lose themselves in the illusion that we have control. Even with all the modern advances in science, we would still be helpless against the simple phenomenon of two rocks hitting each other. I’m glad this one avoided an impact, it’s fortunate for us that the odds of one actually hitting are quite low.
