near miss asteroid
Phil Plait says "Don't Panic!" and he should know because he is the Death from the Skies!: The Science Behind the End of the World which is about things hitting the earth. The object is called 2014 RC and it was discovered on September 2nd. It will arrive on Sunday.
The object is about 20 meter across, and Phil told me on twitter yesterday that this is roughly the same size as the Chelyabinsk asteroid that made a pass over Russia last year.
Remember. Random events occur in clusters. Otherwise they would be called "regular events." So there is probably no meaning to two similar objects…
