What is the Meaning & Definition of Supermoon

ADS

There's a moment each month in which the Moon is the closest distance possible with respect to the center of the Earth in its rotation around the Earth movement. Then it is known as perigee. The phenomenon known as Supermoon, in which the moon appears still larger occurs when lunar perigee coincides with the full moon phase.
The Supermoon is an optical phenomenon, since an observer perceives it with a greater than the actual size. As a result, the appearance of a Supermoon has two reasons: physical one and the other related to visual perception. From the point of view of the movement, the moon rotates on itself and at the same time around the Earth in a translocation who has a form of elliptical orbit. However, the center of the orbit is not equal to the center of the Earth and, in consequence, the distance of the Moon and the Earth is not constant. This aspect of the lunar motion, determines our optical perception at the time that coincides the perigee and full moon.
The superlunas occur periodically, since they occur between three and five times a year (in a year there are between 12 and 13 times in which there is a full moon).

The visual perception of the supermoon

The brightness of the Moon is significantly higher when there is a supermoon, since the perception of brightness changes to find the Moon at a distance less than usual. This optical effect conveys a peculiar feeling, it seems as if the Moon could almost touch. Astronomers have indicated that this optical phenomenon is most intense when the Moon is observed on the horizon. In this way, the perfect moment to observe the supermoon would shortly before dawn, when it is closest to the horizon line.

The Moon in the language

The Moon exerts fascination on lovers, poets and astronomers. The influence of the moon also appears in the language. Lovers who marry celebrate their marriage on a honeymoon. When someone is living a moment of fulfillment, and happiness you can tell that it touched the moon with your fingers. If someone is not concentrated in what is is because it is on the moon. He is called rare people crazed times. This influence of the moon on the everyday language has an explanation: our natural satellite transmits ideas and feelings which then translate into words.
