Asteroid 2012 DA14, NASA says, will be about 17,200 miles from Earth.
An asteroid that is about 150 feet in diameter is expected to fly by Earth early Friday afternoon. While NASA says there's no chance that asteroid 2012 DA14 will hit Earth, the asteroid is expected to pass between Earth and its ring of geosynchronous weather and communications satellites. "The flyby of asteroid 2012 DA14 is the closest ever predicted Earth approach for an object this large," according to the NASA website. "Scientists at NASA's Near-Earth Object Program Office in Pasadena, CA, estimate that an asteroid the size of 2012 DA14 flies this close every 40 years on average and that one will impact Earth, on average, about once in every 1,200 years."

The most reliable meteor shower of the year, the Geminids, is on its way – with no moon to obscure the show.
The Geminid meteor shower 2012, the final major meteor shower of every year and likely to be the best, peaks overnight Dec. 13 and Dec. 14, and you may be able to see a great show on either side of those dates. If you liked the Perseids meteor shower 2012 in August, you should love this show. NASA reports that the Geminids are a relatively young meteor shower, with the first sitings occurring in the 1830s with rates of about 20 per hour. Over the decades the rates have increased, regularly spawning between 80 and 120 per hour at its peak on a clear evening. How spectacular is it? Just take a look at this video of the Geminid meteor shower. You can also look at some spectacular photos of the Geminids. Earthsky.org reports the Geminids peak …
