Russian Meteor

The meteor that landed near Chelyabinsk, Russia on Feb 15, 2013 03:20:26 UT (09:20:26 YEKT, 15.13919 UT) definitely wasn't 2012 DA14 which was observed later on the day at 15.875036 UT. In the 1951 movie, When Worlds Collide, the world is struck by a rogue planet, Bellus, which had a smaller companion, Zyra. The lesson that might be drawn from this is that even though the asteroid that we are focused on may miss the Earth another object can still strike it.
