Sputnik and space probes are artificial satellites
A moon is a natural satellite, as opposed to an artificial satellite, which is a man-made object in orbit.
An artificial satellite is a man made object that orbits a planet or a moon.
A satellite is any object in orbit. An artificial satellite is specifically placed in orbit by human endeavor.

A moon, when referring to a natural rock like satellite, not a man made artificial satellite such as Telstar.
The only artificial satellite launch to take place in 1975 was in India. This satellite was called Aryabhata. Sputnik was the very first artificial satellite to be released, it took place on October 3, 1957.
A satellite is an object that rotates around a bigger object in the sky. For example the planets in the solar system apart from Mercury and Venus have natural satellites, these can be moons and asteroids caught in the orbit. The Earth's moon is one example of a natural satellite. However artificial satellites are built on Earth and are then taken into orbit by rockets or they can be released by a space station.One is natural, the other is artificial. Artificial means "man-made"; natural means it's not made by humans.There is exactly one (1) natural satellite of the Earth, popularly referred to as "The Moon".Any other satellite of the Earth is artificial, manufactured on the surface, by people,then launched and guided into Earth-orbit by rocket-propelled vehicles. This was neversuccessfully accomplished until 1957.
