It’ll pass within the moon’s distance from Earth – closer than the orbits of geosynchronous satellites. But it won’t strike us in 2013.
A near-Earth asteroid – called 2012 DA14 by astronomers – is passing very close to Earth today (February 15, 2013). Astronomers estimate that, when it’s closest to us, it’ll be within the orbit of the moon (which averages about a quarter million miles away), and closer than some high-orbiting communications satellites. 2012 DA14 will be about 17,200 miles (27,680 kilometers) away. Reuters is reporting than a meteorite has struck in Russia, injuring 500 people. It has not been confirmed whether the meteorite is associated with asteroid 2012 DA14, but astronomers do known that asteroids sometimes are accompanied by moon, or travel in swarms.
The main asteroid – 2012 DA14 – is not expected to strike us in 2013, NASA says. There was a remote possibility it might strike us in 2020, but that possibility has been ruled out also.
What will happen when Asteroid 2012 DA14 passes closely in 2013?
Most of us won’t see the large asteroid 2012 DA14 or be aware of its passage, in any way. 2012 DA14 is not large enough to alter the tides. It won’t cause volcanoes. It’ll just sweep closely past us – as millions of asteroids have done throughout Earth’s four-and-a-half-billion-year history – some in your own lifetime. It appears, however, that asteroid 2012 DA14 was accompanied by another object, which astronomers did not detect until it struck in Russia, injuring hundreds.
Asteroid 2012 DA14 will be within range for small telescopes and solidly mounted binoculars, used by experienced observers who have access to appropriate stars charts. Indonesia is favored for viewing, because it will be the middle of the night there when the asteroid is closest. Europe and the Middle East will also be in a location to view the asteroid, potentially. But this will be a challenging observation. Even those familiar with using binoculars and telescopes will need some experience to track the object as it moves rapidly across the sky.
Study Claims Cave Art Made by Neanderthals 2014 09 02 A series of lines scratched into rock in a cave near the southwestern tip of Europe could be proof that Neanderthals were more intelligent and creative than previously thought.
The cross-hatched engravings inside Gorham’s Cave in Gibraltar are the first known examples of Neanderthal rock art, according to a team of scientists who studied the site. The find is significant because ...

LA Times Now Describing Illegal Aliens As ’Informal Workers’ Who ’Labor Unofficially’ 2014 09 02 Via Weasel Zippers, we learned the Los Angeles Times has a new term for illegal aliens in the work force: they’re “informal workers,” and that doesn’t mean they don’t arrive on the job in a tuxedo.
Times reporter Tiffany Hsu (a "UC Berkeley grad") began her Saturday story with the new I-word (and illegal immigrants also “labored unofficially” in "gray employment"):
