The space age, from its first year
On 4 October 1957, the Soviet Union launched Sputnik 1—the first artificial Earth satellite. The chart starts there and counts registered objects launched into outer space, not only active satellites.

What these numbers mean
A launched object may later re-enter, stop working or fragment. That is why total launched, still in orbit, functioning satellites and tracked objects are different figures.
