Asteroid Fly-By

This Friday we'll be watching the ASTEROID FLYBY: At 12:25 pm (MT) on Friday, Feb. 15th, asteroid 2012 DA14 will fly past Earth only 17,200 miles above our planet's surface. This will put it well inside the orbit of geosynchronous satellites, closer than any asteroid of the same size has come since regular sky surveys began in the 1990s.

We'll be watching it on NASA TV later in the day. 

Here's a simulation of the fly-by...
