The word "asteroid" was used for the minor planets (the new class that was invented at the same time, when the four lost their planet status), as long as they did not show a disk. Meteorite remains are buried at an 80-meter depth.

While some of the 5-15-metre-long replacements for NASA’s space shuttle are visible to the naked eye as they reach and settle in to orbit, by far the coolest human-made thing to see in the night sky is the International Space Station. They are relatively small, composed mostly of rock, and have few or no moons. Infrared cameras showed large explosions occurring as each fragment hit, and as Jupiter rotated around, we could see dark cloud features, sort of like cosmic black eyes, on the clouds.
