Update on the Russian Meteor - a cosmic warning shot?

CSI Space? It is always impressive to read the science and investigation of all things celestial. However, I do not have the tools at my disposal to verify or disprove. I thought I would pass on this interesting online article in follow up to the Russian meteor event: Russian Meteor Likely An Apollo Asteroid Chunk posted in Discovery.com

I had posted regarding Close call documented. AP PHOTOS: Meteor explodes over Russia - Nation Wires - Miami Herald.com. Fox News historical reference of 1908 Tunguska event.

The article identifies the meteor by type, labeling it an Apollo asteroid, stating that the group is a well-known near-Earth asteroids that cross the orbit of Earth. Around 5,200 Apollo asteroids are currently known, the largest being 1866 Sisyphus — a 10 kilometer-wide monster that was discovered in 1972.

Large Apollos are identified as being a significant risk to our planet, so the Chelyabinsk meteoroid acted like an Apollo warning shot.
