Those may be fragments of same asteroid, notice how small they are, most wouldn't survive through our atmosphere, maybe 2012 XM16 (32m) could. The
asteroid which probably caused Tunguska event was ~10 meters, smaller than this won't survive, but it depends on their speed and angle.
There is one very close approach coming in Feb 15th, when 35-79 meter wide object named 2012 DA14 will pass only 0,09 Lunar distance away (20 700km),
which is closer than some satellites.. That would be VERY close call. If its 79m in diameter, it could be really dangerous, equivalent of many
hydrogen bombs. It isn't dinosaur extinction object size (which was ~10 km wide), but large enough to destroy whole regions.
