Well that depends on if are talking about artificial or natural. The first artificial satellite was the USSR's Sputnik 1 so you could credit the Russians with that.

If you mean natural then we have go WAY back. 2500 years ago to Babylonia, they knew celestial objects seemed to 'move across the sky' and come back to the same position a year later: the only conclusion was that they circled the earth.

It wasn't until 1609 when Galileo, using a crude telescope, actually saw the moons of Jupiter clearly circling the planet. He deduced that earth along with the other known planets must be 'orbiting; the sun.

How was the satellite invented?

The idea of an artificial satellite goes back at least as far as the prototype science fiction story "The Brick Moon". The idea that actual, real satellites could perform useful work goes back to about 1947, when science fiction author Arthur C. Clarke realized that satellites orbiting the equator at about 22,000 miles out, would appear not to move in the sky. You could aim an antenna at it and leave it. Thus you could make communications satellites that could transmit a signal from anywhere on Earth to anywhere on Earth, just by having 3 satellites spaced around the Earth. The first actual, real satellite was Sputnik, sent up by the Russians in the late Fifties.
