The Moon is the natural satellite of the Earth, which can be admired from the previously mentioned planet in a greyish whitish way with some craters as decoration, it has earned several sighs from poets and authors, even for some tribes the Moon arrives to be a goddess of fertility and love.

  • Distance to Earth:  384 400 km
  • Gravity:  1.62 m / s²
  • Orbital period: 27 days 7 hours and 43 minutes

What is the Moon?

The Moon is generally defined as the only existing natural satellite  that is attached to the Earth. It has a diameter of 3474 kilometers and is counted as one of the largest satellites in the solar system, specifically the fifth largest satellite in the solar system.

How the Moon was formed

It is said that it was formed after the origin of the solar system in the universe we inhabit, a great impact of massive destruction was created between what was a celestial body of a size compared to that of Mars with the Earth, destroying its material in orbit, the hypothesis assumes that the remains of this impact coalesced with each other in the form of molten magma, creating what is the  Moon.


The molten and lived magma that had been left by the collision of the celestial body with the Earth, after 100 million years crystallized, thus forming the lunar crust, giving the visual shape to the Moon that we know today.


Some of the most relevant characteristics of the Moon are the following:

  • Mass: 7.3477 x 1022 kg.
  • Volume: 2,197 x 1010 km3.
  • Density: 3.344 g / cm3.
  • Diameter: 3,476 km.
  • Minimum temperature: -233 ° C
  • Maximum temperature: 123 ° C
  • It is considered the natural satellite of the Earth.
  • It can be seen from the Earth in a whitish, grayish way with some craters embedded in it.
  • It was formed from an impact between a celestial body the size of Mars and Earth.
  • It is considered the fifth largest satellite in the solar system.
  • It is at an average distance of 384,400 kilometers from Earth.
  • After the sun, it is the brightest thing that the human being can witness.


It is expected that for a couple of centuries the Moon will continue to be linked with the Earth, since it is part of it, however, it will be far away, so it can no longer be observed from the view of the Earth, being its Orbit changed , it is currently moving 4 centimeters per year from the Earth, increasing its distance.


The phases of the Moon are as follows:

  • New Moon.
  • Crescent moon.
  • Crescent quarter.
  • Crescent gibbous moon.
  • Full moon.
  • Waning gibbous moon.
  • Last quarter.
  • Waning moon.
  • Black moon


The Moon is located at an average distance of 384,400 kilometers from the Earth, it must be emphasized that after the sun, which is a star , it is the brightest body that can be seen from the surface of the Earth.

Rotational movements and translational movements

This is in constant motion , although human beings are not aware of it, since it is almost as imperceptible as the rotation of the Earth, however, the Moon performs a total orbit style around the Earth for 27 Earth days , which for space would be summarized in 27,322 days or 655,73 hours, its rotational movement is based on the same speed, in constant synchrony with the Earth, always presenting the same face to the Earth, that is, that people They can only observe a part of the Moon, so the changes that can be noticed in this are the effects caused by clouds or climate changes , however,Thanks to the advances and evolution of science , the finding was obtained that the other side of the Moon is made up of much deeper craters , depressions called thalassoids and the absence of seas and lunar lagoons.


It has been observed since the beginning of humanity , even animals delight in its beauty, one of the animals most attached to the Moon are wolves and dolphins , it is highly renowned in ancient nations and civilizations , in the same way It is part of the mythology of many regions, it is constantly admired, it influences the climate, the terrestrial cycles and in the same way to human beings , having an almost magical effect on everything that observes it carefully, as if really instead of being a satellite was a goddess .


On July 20, 1969 , it happened that twelve American men who were dedicated to being astronauts, embarked on the Apollo mission , walking in this way on the lunar surface at that time, however, this project was postponed and resumed in 1990 .

Influence on the tides

The influence of the Moon on the oceans is peculiar , thanks to the attraction of gravity and its constant synchrony with the Earth, this causes the tides, which accidentally and by inertia causes what is known as a marine undertow , since the forces of attraction They go in the opposite direction , causing the shock and constant movement of the sea, resulting in high tide and low tide.

Influence on humans

It has not yet been scientifically proven that the Moon has any specific effect on the behavior of human beings, although there are many theories that it speeds up mental processes and develops the production of endorphins and serotonin, in addition to this, the only thing that is It has been scientifically proven that this has a certain influence on what the sleep processes are and how they manifest themselves.

Importance of the Moon

The Moon is a natural satellite, which since its formation became part of the Earth , so that it is no longer conceived without it ; There is great concern about what is the distance that is gradually taking place year after year from the Moon with the Earth , the authors who love this are dismayed because of this, since many are inspired by it.
