A small (4-5 meter) asteroid discovered earlier today by R. A. Kowalski of the Catalina Sky Survey will pass by Earth on Feb. 4th around 19:40UT at a distance of 11855 km. 2011 CQ1 will not hit Earth, but it will pass well inside the Clarke Belt of geosynchronous satellites.
6,000 to 12,000 miles - Asynchronous Orbits For navigation, the U.S. Department of Defense built the Global Positioning System, or GPS. The GPS uses satellites at altitudes of 6,000 to 12,000 miles to determine the exact location of the receiver.

That is what I was thinking. Even if it doesn't strike an active satellite, it could strike and/or disorient all of the other space junk lying around and cause a shower to come into the atmosphere, or cause junk that is being tracked to suddenly change trajectory and put the ISS or other things in danger.
Asteroid 2011 CQ1 was discovered by the Catalina Sky Survey on February 4 and made a record close Earth approach 14 hours later on February 4 at 19:39 UT (14:39 EST). It passed to within 0.85 Earth radii (5480 km) of the Earth's surface over a region in the mid-Pacific. This object, only about one meter in diameter, is the closest non-impacting object in our asteroid catalog to date. Prior to the Earth close approach, this object was in a so-called Apollo-class orbit that was mostly outside the Earth's orbit. Following the close approach, the Earth's gravitational attraction modified the object's orbit to an Aten-class orbit where the asteroid spends almost all of its time inside the Earth's orbit.
