This little item just in from Space Daily. Seems a little 5 meter wide asteroid called 2004 YD5 zoomed “just under the orbits of geostationary satellites, which at 22,300 miles (36,000 kilometers) altitude are the highest manmade objects circling Earth” and no one noticed until after it had passed by. Turns out it approached sunward (right in our blind spot), flew over Antarctica, and continued merrily on its way. Astronomers spotted it after it had passed us by.
Did anyone remember to duck?
