Amazing facts of the moon

The moon is not simply a light that shines in the middle of the night or a dazzling look that enchants the viewer, it is more and it will undoubtedly be produced by yourself after reading the amazing facts that concern it .

What is the moon?

Before the telescope was discovered in the early seventeenth century, the moon was only a circular, mysterious and astonishing thing at night, but scientists later discovered that the moon was not not a very strange Earth and that other moons gravitated around other planets.

The Moon is known as a continuous orbiter around a planet, including the eight main planets, dwarf planets and small planets, and can be described as a "natural moon" with respect to any artificial satellite. The object called the Moon is different from any other astronomical body. Circulation, thanks to its unique feature of being a satellite of a planet.

The first satellites to detect the moon are the satellites of Jupiter called Galileo, based on the astronomical world of Galileo Galilei. Satellites such as Calisto and Ganymede are one of the largest satellites on the planet and one of the oldest known satellites on the planet, with 63 satellites.

Saturn Titan and Neptune's Triton, one of the closest satellites to the moon, are the largest satellites in the solar system, while Mercury and Venus are the only planets not to possess satellites.

What is the moon?

The outer surface of the moon consists of dead rocks and volcanoes, volcanic eruptions and drilling resulting in collisions with other models.

Scientists thought that the dark expanses of the moon were actually oceans, but they are not natural oceans but contain a solid lava.

It is said that at the beginning of the Moon's history, its inner layers have melted enough to produce volcanoes and lava. This lava froze and quickly lost heat, but another lava continued to appear when it penetrated the asteroids deep enough to the surface.

The appearance of the outer moon shows the existence of these collisions with asteroids and other models in the space, where we can see them because the moon does not have defenses such as the atmosphere and the tectonic and other plates of the planet to cover these ancient effects.

In terms of its internal components, it has a crust such as the earth and a layer of soil called envelope or membrane. The moon would have a solid iron core surrounded by an outer core of molten liquid iron that can extend up to 500 km. About 50% of all Moon components are generally rocky particles. The inner part of the Moon consists of a 1000 km rock cover, solubility in the early years of the Moon, and the cause of formation of the materials. base for the release of lava on the surface.

How big is the moon?

The diameter of the moon is about 3,474 kilometers, which means that it represents 27% of the Earth's size, while the planet has 12,742 km.

That's the surface of the moon 37.9 million square kilometers, smaller than Asia alone 44.4 million square kilometers, while the lunar mbad is about 7.347 x 10²² Kg.

It should be noted that the total size of the moon is 21.9 billion cubic kilometers, which is more than 2% of total land area

Phases of the moon

The different phases of the moon occur around the Earth, namely:

• The sirup: The first phase is at the level of the alignment of the sun and the moon, and can not be seen at this point because we only see the dark side.
• Hilal: The first intermediate step, we can see the moon in this case in the afternoon and after dusk, and only a small part of it appears after the end of the eraser phase.
• Growing quadrature: The next major phase of the Moon phases, has pbaded on this place the first quarter of its Earth orbit and is only visible by 50%.
• Hump ​​more and more: The second intermediate step that continues until the next phase (or the next main step) and the shape of the moon is almost clear for the vision.
• Al Badr: We see the entire moon at this stage of the night and when we cross this state of the shadow of the earth, we call a lunar eclipse.
• Humpback hump: Next intermediate stage and low visibility of the moon.
• Decreased quadrature: We can only see half of the moon at this point, but we see a half that was not visible during the increasing squaring.
• Ascending descending: The sun illuminates less than the previously visible half, so visibility drops to just under half

Interesting facts about the moon

Here are some highlights on this distinctive theme:

• The dark side of the moon is a myth because sunlight reaches the sides of the moon, but from the Earth's point of view, we can only see one, because the moon revolves around the moon. 39, itself with the same speed around the Earth.
• The moon is one of the main causes of the tides and it directly affects the strength of the increase and decrease of these phenomena.
• The Moon is gradually moving away from the Earth by 3.8 centimeters a year and is expected to continue for about 50 billion years, but it will take 47 days to complete the Earth's cycle instead of the 27.3 current days.
• The gravity of the moon being much lower than that of the Earth, the weight of the man is also lighter on the moon and equal to that of any person standing on its surface, about 16,5% of its real weight in floor.
• Neil Armstrong was the first person to walk on the moon in 1969 and the last person to be Gene Cernan in 1972. A total of 12 men, all men, followed by self-propelled vehicles.
• There is no atmosphere in the moon, that is, it is not protected from pbading meteorites and asteroids, and its temperatures are very volatile and can not be heard and the sky is always black.
• Due to Earth's gravity, earthquakes occur on the Moon and astronaut tests on the surface show that it is subject to small tremors a few kilometers from the surface.
• The first spacecraft to reach the moon is a ship of the Soviet Union, the Luna 1, in 1959.
• The moon is the fifth largest natural space satellite in the solar system.
• There is a dominant theory that the moon was part of the Earth and was separated as a result of the collision of a large object at a young age.
• NASA plans to send more astronauts to the moon and create a stable space station on it.
• In the 1950s, the United States planned to detonate a nuclear bomb on the moon. This secret project of the Cold War period aimed to examine the power of the United States at a time when it was lagging astronomical race and space studies.
