I don't know, the current GPS system has 30 operational and healthy satellites.
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?
Mars has 2 satellites that orbit around the planet. These 2 satellites are not man made. These satellites are naturally made of rock.
Natural satellites are things like our own moon that orbit a planet.In our solar system there are 173 natural satellites that we know of.
there has been 7 man made satellites sent to Saturn.
There are currently no man made satellites or robots on the planet Neptune.
A system made of 25 satellites is called global positioning system (GPS).

Satellites can be natural, and satellites can be man-made. They cannot be both. Satellites are either natural or man-made.
Jupiter, with 63 satellites.
None. By definition , our "solar system" is everything controlled by the gravity of our sun. The planets, their satellites, asteroids, dwarf planets, comets, interplanetary dust, and man-made satellites are "within" our solar system. Any "planet" outside out solar system is just that - OUTSIDE of it.
Satellites are man made objects, they can not "evolve".
All the planets have satellites, except Mercury and Venus.Jupiter

Mercury and Venus do not have any natural satellites.
They are the only satellites known in the solar system to have substantial atmospheres.
Most of the satellites are for communication - such as tv/radio and mobile phones. There are also the satellites of the Global Positioning System and military satellites.
