The first successful launch of an artificial satellite took place in October of 1957. There were none in space until then, and exactly one for the remainder of that year. So it's a pretty safe bet that there are more now.
The Moon is the natural satellite of the Earth, so the person who discovered it was probably Ugghhh, the First Caveman. Artificial satellites weren't developed until the 1950's, and so the "discoverer" was one of the Soviet engineers who launched the first Sputnik, the first artificial satellite of the Earth. Other planets have their own satellites. Galileo is credited as discovering the four largest satellites of Jupiter in January, 1610, when he pointed his new telescope at Jupiter.
The first artificial satellite was Sputnik I, launched by the Soviet Union on the 4th of October 1957
