One natural one and literally hundreds of man made satellites. The actual number is probably a secrete.

We have many artificial ones ranging from space stations to junk. As for natural ones, we have two at least. The first being the Moon and the second was discovered a few years back. The second one does not have a name as far as I know. It is no more than a rock(probably a captured asteroid) but it is in a stable orbit and there for can be considered as a satellite.

One natural; the moon. Tens of thousands of man made if you count all of the nuts and bolts and other debris left behind over the last 60 years of space flights.
By the way a good project would be to tell how NASA is tracking all of the space debris so that the Shuttle won't run into any of it. Link below.

Natural ones, just the moon. Man made I have no idea but they must be dozens.
