On February 15, 2013, the planetary science community eagerly awaited the close flyby of near-Earth asteroid 2012 DA14, which passed inside Earth’s geostationary satellite ring. However, several hours prior to its arrival, a 17-20 meter asteroid exploded high above Chelyabinsk, Russia. This presentation will provide the latest information about these two asteroids, the effects of the impact event on the ground, and why the Chelyabinsk asteroid was not detected prior to its encounter with the Earth.
