What the Moon is for the average inhabitant of our planet? Night beauty, brighter than the other lighting the sky, when the lights go out. Young sickle or a complete sphere, usually weighing over his head and shrouded in countless legends, known to most from school. To an astronomer the Moon — the most studied celestial body, only attended by people, and at the same time remains mysterious. In astrology, the satellite of our planet — one of the most important celestial bodies that have a significant impact on people's lives. This article provides several answers to the question "what is the Moon": the definition from the point of view of astrophysicists, the understanding contributed by the drafters of horoscopes.
From time immemorial
People were interested in the Moon throughout its history. This is not surprising: such a beautiful object in the night sky are hard to ignore. Already six centuries before the Christian era, the ancient scientists in China and Babylon knew about the main features of the behavior of the satellite of the planet. They watched the changing moon face and measured the interval between the same phases (29.5 days), could predict the next Eclipse of the moon. Was compiled calendars of the shift phases for the different regions of the Earth. As Pythagoras already in the IV century BC knew that the moonlight is only a reflection of the sun.
Today has accumulated a huge amount of data about the earth's moon and more or less explain in detail what the Moon is, may be any student. The closest to our planet is a space object was constantly the center of attention of astronomers for many centuries. It was on the moon first landed astronauts, adding to the already accumulated data, new interesting information. So, taken soil samples after a detailed study of caused review the main existing at the time the version of the education companion. Was launched the so-called giant impact hypothesis. According to her, about 4.5 million years ago, the young Earth collided with the protoplanets, comparable in size with Mars. The result of the impact has come not in the center, and on the edge, was knocked out the clot of substance, consisting of separated from both bodies of matter. From it under the influence of gravitational forces on the orbit has formed a new young Moon.
This version of the origin of the satellite to date, remains the most probable, according to scientists. However, there are a number of issues to resolve in the framework of such a theory is impossible. The origin therefore remains one of the mysteries of the satellite.
The moon turns around the Earth in an elliptical orbit in 27.32 day (sidereal month). The average distance from it to our planet is 384 467 km. the trajectory of the moon is exposed to several changes:
- precession or plane rotation (period 18.6 years);
- tilt change relative to the ecliptic (from 4 ° 59 ′ to 5 ° 19 ′);
- the rotation of the major axis of the orbit (the period 8.8 years)
- changes the size of the orbits, resulting in periodically moving the points of apogee and perigee.
In addition, the moon and the Earth interact. The so-called tidal forces — the external expression of this. In addition to the periodicity of the movement of ocean water, they have another consequence: the angular momentum of our planet is transmitted to the satellite and it is gradually removed from us. Each year, the distance from the moon to the Sun is rising by about 4 cm, However, with the removal of the satellite, the speed of "escape" is reduced.
As already mentioned, the Moon does not Shine itself. The observer on Earth is able to see her due to the reflection of the moon's surface is sunlight. All three objects interacting at the same time – our planet, the day star and the Moon are constantly in motion. The satellite is in the shade, "coming to light". As a result, the sky it appears a month or a full circle, and sometimes completely absent.
What is the phase of the moon? This is the kind of face of the satellite, corresponding to a certain angle between it, the Sun and the Earth. There are four main phases:
- New moon. At this time, the satellite is absent in the sky, its reverse side is illuminated.
- First quarter. The moon is half visible.
- Full moon. The moon appears before the earthly observer in all its glory.
- Second quarter. The satellite is again half visible.
What is a waxing Moon? This is the time when the new moon is becoming more visible, breaking the first quarter, approaching the "climax" of the cycle. To determine this period, you can, if you take a hammer to the finger. During the growth of the moon formed the letter "P". If the month is similar to C, it decreases.
What is a waning moon? This is the period when the satellite begins to "thaw", slowly decreasing in size until it disappears completely.
Some interesting moments
With the change of phases associated with the phenomenon of ashen light. During the descending and the rising months are often seen pale the rest of the disk. It is illuminated by sunlight reflected from the Ground first, and then, secondarily, from the moon.
Moon in astrology
In the preparation and reading of horoscope earth satellite plays an equally important role as the Sun. A significant position, they owe their physical parameters. Astrologers since ancient times guided by the principle "what is above resembles what is below", so is visible from the Earth the Sun and the Moon have in their opinion a huge tangible impact on people's lives.
Night light symbolizes the soul and is associated with the sensual side of the personality. Since ancient times, he is credited with the ability to manage mood and emotion, which finds its confirmation in some medical research. Like its physical counterpart of the astrological Moon is fickle and incapable of direct creation: it does not Shine, but reflects. Its position in the horoscope determines the habits of man, his affections and reactions. Together with the Sun, the Moon affects the formation of character and the ability of the child to adapt to the environmental conditions on the functioning of the organism, a condition.
What is a Black Moon?
In addition to the physical planets, which include the Orb of night, in astrology, there are also hypothetical (perhaps existing, but not yet open) and fictitious (their physical equivalent, most likely, does not exist). The latter include the Black (Lilith) and White Moon (Selena).
The name Lilith in astrology represents the apogee of the moon, the point at which it is maximally removed from the Earth. The Black Moon is associated hidden desires, suppressed desire, and also illnesses and problems that are associated not directly with the person, and typical of his kind. Astrologers point to the impossibility of direct influence on these aspects. Work with them is conducted through the White moon. This is another fictitious planet, which plays a prominent role in the horoscope.
What is White Moon?
Selenium in different schools of astrology are defined differently. In the classic version it refers to the point of perigee, i.e., closest approach of the moon to the Earth. Selena is the opposite of Lilith in its manifestations and symbolizes everything positive that happens in a person's life. Sometimes the White moon even called Angel. Its effect compensates for the negative influence of Lilith.
The astrological answer to the question of what the Moon is, of course, much longer than the following description. Various aspects of the impact, combined with other planets uninitiated reader will seem incomprehensible. However, the same can be said about the detailed, with lots of numbers and terms, description, existing in astrophysics. In both disciplines during the existence of mankind has accumulated a huge amount of data about what the Moon is and what influence it has on the fate of people and our planet. However, for the ordinary observer, it will always be primarily nocturnal luminary, ornament of heaven, the inspiration and guidelinesa poets and romantics.
