The first artificial satellite- Sputnik- was launched into space on October 4, 1957 by the Soviet Union. Since then, things have been busy! As of August 19, 1999, there is a total of 2616 satellites in Earth orbit, as well as 90 space probes (that is, objects not orbiting the Earth but sent to the Moon, planets, comets, etc.). On top of that, there are about 6100 pieces of debris out there as well: pieces of broken up satellites, rocket boosters, lost tools, etc. etc., for a grand total of roughly 9000 objects in space. The U.S. alone accounts for about 3850 of that total.

your question cannot be answered. Last count in 2001, before more satellites were launched as spy, t.v. and cell phone companies was around 3200. As a planet there are satellites at different levels (miles outside gravity) that will never be known, but in 2008 there will be around 20 satellites a year falling from orbit. Most will burn up on re-entry. I cant tell you how I know this, but a better question would have been how much hardware is wasted to send satellites into outer space. You would be amazed.

I don't know the exact number but there are many, probably hundreds. Just the satellite phone system uses at least 30, then there are other satellite services, such as cable and GPS; also there are spy satellites, telescope satellites (like Hubble), and then weather satellites, and earth imaging satellites, and then commercial communications satellites or whatever else commercial companies can use satellites for. There are many.

There is no true way of knowing, so many of them are classified by military and government
