No, the first man-made satellite was launched in 1957 by the then Soviet Union: The Sputnik-1 satellite.
Natural satellites of courses existed since the creation of our solar system. For example, our moon can also be called a satellite of earth, but you are probably asking about man-made satellites?
You probably mean to ask about natural satellites as opposed to artificial satellites. In terms of neutrality, all satellites are neutral. In any event, the planet Jupiter has the most natural satellites, of any planet in our solar system. The planet Earth has the most artificial satellites.
satellites produce energy by the sun
Mercury has no satellites.
Venus is one of the few planets that doesn't have any satellites orbiting around it. Venus also is a planet with no moons.
No natural satellites of Venus have been discovered.
No satellite did. Pluto was discovered by Clyde Tombaugh, who found it using a ground-based telescope in 1930, long before we launched the first satellites.
The five major types of artificial satellites are: research, communications, weather, navigational, and applications. Please see the related links.
There are no known satellites of Mercury.

It has 3 satellites!
Triangulation of satellites requires three satellites that bank of one another simultaneously.
Those are called planetary satellites or natural satellites. Each planet has its own set of natural satellites that orbit around it.
Elliptical satellites don't have a constant speed, but circular satellites do
All the satellites, communications, exploratory, military etc. are artificial satellites of Earth.
Applications satellites, like weather satellites, communications satellites (TV, Cell phone, internet), military observation birds, reconnaissance satellites and other "useful" things predominate. Purely scientific satellites such as the Hubble Space Telescope are in the minority.
If each ring can hold 3 satellites, you can accommodate all 24 satellites with 8 rings. Each ring would hold 3 satellites, for a total of 24 satellites.
