how many satellites are around earth?
There have been about 8000 man made objects launched into space - only a handful left Earth orbit. Some have decayed and reentered. There are about 3000 satellites currently in orbit. Only about 1000 of those are active. But there are other objects, too, such as spent rockets. Some objects have broken apart because of collisions. There are about 20,000 objects in orbit that are 10 cm in diameter, or larger.
