Astronomy/Satellites Orbiting earth

Expert: Steven LJ Russo - 9/27/2006


Question
Do you know how many operating satellites orbit the earth now?  A ballpark figure would do.

Answer
I got the information below, from a NASA web site:

Did you know there are over eight thousand artificial objects orbiting Earth? Over 2,500 are satellites, operative and inoperative. The remaining objects are orbital debris: parts such as nosecone shrouds, lens, hatch covers, rocket bodies, payloads that have disintegrated or exploded, and even objects that "escape" from manned spacecraft during operations.
