What is Natural Satellites definition/concept

A natural satellite is any celestial body that orbits around a planet. As a general rule the satellite is smaller than a planet. Natural Satellites 

Not all natural satellites are the same, as there are actually solid, shiny, opaque ones and some are quite large. It should be noted that planets can have several natural satellites, so that the satellite and the planet are held together by the force of gravity acting in a reciprocal fashion.

Most planets in the solar system have at least one natural satellite. Mercury and Venus are the exceptions to this rule.

Natural Satellites of the Solar System

Planet Earth has only one satellite, the Moon. On the other hand, Mars has two, Phobos and Deimos. Jupiter is the fifth planet in the solar system and in its orbit there are a total of 64 satellites (Calisto, Io, Ganymede and Europa are among the best known). In relation to Uranus, its satellites are Titania, Ariel, Miranda, Oberon and Umbriel. Natural Satellites 

Saturn’s satellites have more particular characteristics, as their density is very low, they have an intense light and their orbital dynamics are not homogeneous (there are coorbital, pastoral and Trojan satellites). Around Neptune there are a total of 14 satellites, of which Triton is the largest and was discovered in 1846.

In our galaxy some natural satellites call the attention of astronomers for their rarity

Thus, Ganymede has its own magnetic field , Callisto is the one with the greatest number of craters, and Epimetheus and Janus revolve around Saturn in the same orbit. Natural Satellites 

As can be seen, the names of the various celestial bodies are based on Greek and Roman mythology. However, astronomers do not use any mythological name, but look for a relationship between what represents the myth and the star, for example, Helium represents the Sun, as it is responsible for bringing heat and light to Earth.

In space there are also artificial satellites

Artificial satellites are those created by humans. The first artificial satellite sent to space was Sputnik, launched in 1957, in the context of the so-called space race between the Soviet Union and the United States. Sputnik had a telecommunications system that emitted radial signals that could be received on Earth. Natural Satellites 

There are currently around 2,500 active satellites for scientific, military, meteorological or telecommunications-related purposes. Anyway, artificial satellites make it possible to establish communication between two people located anywhere on the planet.
