September 2014: Asteroid Discovered Just Days Ago Will Approach Closer Than The Moon This Weekend
Adam Rifkin stashed this in @iflscience
Asteroid 2014 RC — nicknamed Pitbull — will be making its closest approach to Earth on Sunday, September 7. This 20-meter-wide asteroid will be passing just 40,000 kilometers (25,000 miles) away, which is roughly a tenth of the average distance to the moon. Two observatories independently observed the asteroid just days ago during Labor Day weekend.

It's not going to impact Earth but:
This one is about the same size as the one that hit in Chelyabinsk, Russia (20m) and that one had kinetic energy that was 20-30 times the amount of the atomic bomb dropped in Hiroshima. I'd say that could potentially cause a fair amount of damage
It's amazing that they only just discovered this asteroid now. Haven't they been paying attention??
Worse, what if there was no way to know?!
Well then we aren't as far advanced as we think we are.
