The 1st known conception of artificial satellites came from the American Edward Everett Hale in a short story called "The Brick Moon" serialised in The Atlantic Monthly in 1869.
The Russian Konstantin Tsiolkovsky in 1903 published "The Exploration of Cosmic Space by Means of Reaction Devices". He 1st proposed the use of rocketry to launch satellites into space. He even made an attempt to calculate the speed of orbit of an artificial satellite.
The Slovenian Herman Polocnik in 1928 1st proposed the idea of humans living in space stations in his publication "The Problem of Space Travel --- The Rocket Motor". He calculated the distance of geostationary orbits.
The idea of a network of communication satellites came famously from Arthur C Clark in an article called "Wireless World" in 1945.
Sputnik 1 started when Sergey Korolyov proposed the idea of artificial satelites orbiting earth to the then soviet defence minister Dmitriy Ustinov in 1954. 3 years later Sputnik was launched.
The difference between an artificial satellite and a natural satellite is on how they are made. Electronic Satellites that are made by man launched into space are Artificical Satellites, while the Moon which is not artificially made are called Natural Satellites.
Satellites of the Earth are held in their orbits by the Earth's gravity. That includes the Moon and all the artificial satellites etc. that are up there.
Most moons orbiting the various planets of our solar system are considered "satellites" - more specifically, "natural satellites". In addition, the more general use applies to the various space modules, etc., orbiting around the earth or around other planets of the solar system. As they are the result of human device, they are considered, "artificial Satellites". Sputnik 1, as the very first of these, acts as prime example.
Satellites cannot orbit one country. They may remain in geostationary orbit, but only at the equator. Therefore no satellite stays above only New Zealand.
Artificial Intelligence
over a thousand artificial satellites. the first artificial satellite was sputnik. the only natural satellite earth has is the moon
Sputnik-I
First was sputnik, but anything from the Direct TV and XM radio satellites and telecommunication, GPS to the International Space Station are artificial satellites in Earth Orbit. There are artificial satellites currently in orbit around other planets as well.
All the satellites, communications, exploratory, military etc. are artificial satellites of Earth.
The five major types of artificial satellites are: research, communications, weather, navigational, and applications. Please see the related links.

Venus has no natural satellites. It does have two artificial satellites (space probes). Venus is one of the two planets in our solar system (together with Mercury) that have no moon/natural satellite.
Uranus has 27 known artificial satellites as of now. These satellites are typically referred to by numbers rather than names.
There are two kinds of satellites: the artificial and natural satellite.
Mercury has no natural nor artificial satellites.
Sputnik and space probes are artificial satellites
We have used artificial satellites in order to take pictures and study the moon and they did travel around it.
