How many man-made satellites are orbiting Earth?

1 Answer

Astronomically, a satellite includes anything that orbits the Earth and that includes everything from the earliest space missions up till today...

Explanation:

Man-made satellites, where I assume you mean spacecraft designed for a specific purpose and not space debris that was man-made, stands at around 2,500 spacecraft at last count (in 2010).
