Asteroid tracking. Source
On February 15, this Friday, the asteroid 2012 DA14 will fly very close to Earth. There has been a lot of talk about this asteroid because it is going to pass within the orbit of our highest satellites, but it will not hit us. The probability of impact is something on the order of 0.0000064, the actual statistics can be seen here. I was hoping to be able to see the flying rock at 2:24 p.m. ET, but sadly it is too small for the unaided eye to see. If you have a telescope and live in the region between Eastern Europe and Australia, you have a chance of catching a glimpse as it flies off toward the sun.
