UGH
I'm glad that wasn't the headline for the release about 2011 CQ.

Anyway, there is a bit of discussion about this object ove ron my Minor Planet Mailing List, including the possibility thatthis might be some old space junk returning.

List members here might be interested in some animationsPasquale Tricarico at the Planetary Science Institute put together. Pretty cool seeing how much the orbit is changed by the encounter with the earth.

Trajectory of 2011 MD projected onto the Earth's orbital plane. Note
from this viewing angle, the asteroid passes underneath the Earth.

Trajectory of 2011 MD from the general direction of the Sun.
Near-Earth asteroid 2011 MD will pass only 12,000 kilometers (7,500
miles) above the Earth's surface on Monday June 27 at about 9:30 EDT.
The asteroid was discovered by the LINEAR near-Earth object discovery
team observing from Socorro, New Mexico. The diagram on the left shows
the trajectory of 2011 MD projected onto the Earth's orbital plane over
a four-day interval. The diagram on the left gives another view from the
general direction of the Sun that indicates that 2011 MD will reach its
closest Earth approach point in extreme southern latitudes (in fact over
the southern Atlantic Ocean). This small asteroid, only 5-20 meters in
diameter, is in a very Earth-like orbit about the Sun, but an orbital
analysis indicates there is no chance it will actually strike Earth on
Monday. The incoming trajectory leg passes several thousand kilometers
outside the geosynchronous ring of satellites and the outgoing leg
passes well inside the ring. One would expect an object of this size to
come this close to Earth about every 6 years on average. For a brief
time, it will be bright enough to be seen even with a modest-sized
telescope.
