"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."
