In a few days, the moon will come closer to us than usual. In fact, she has not been so close decades. On November 14th, we will be able to observe the largest supermoon in almost 70 years. According to NASA, "it will be full in about two hours of perigee," as it is called the point of the orbit closest to the center of our planet.

But what is the phenomenon about? Supermoons are just a coincidence, British astronomer Heather Couper told the BBC. "The moon moves around on an elliptical orbit, so it can come very close to us and, if that matches with a full moon, then it can seem absolutely enormous," she explains.

The supermoon will happen 14 November

This coincidence will happen on November 14th and will be extraordinary this time.

On this occasion, the Moon will be 48,280 kilometers closer to the Earth than when it was recently at its peak, the furthest point in the orbit.

With the exception of the super-moon eclipse of 2015, there has not been and will not be a full moon so special in a long time (even though there are three consecutive supermoons in the last three months of the year: the last occurred on October 16th and the last will be December 14th).

What is the best way to see a supermoon?

First, of course, is to move to an open and peaceful place, away from big cities and artificial lighting. Like any full moon, the celestial body is bigger and extremely bright if observed when it appears on the horizon. Although super-moons look 14 percent larger and 30 percent brighter than ordinary full moons they are even more surprising when they are on the horizon and not high in the sky.

The expert from the United States Naval Observatory (USNO) Geoff Chester explains that this is the result of an optical illusion, as quoted by NASA. This is an optical effect that astronomers or psychologists do not fully understand. Couper adds that supermoons seem even larger when viewed through trees or houses.

Surprises to discover on a super-moon

The moon has plenty of craters caused by meteorite impact and, it is believed, possibly by volcanic activity billions years ago. The contrasts between areas that reflect sunlight (mountains) and the esplanades that remain in the shadows (the seas) can be converted, using a little imagination, in the most amazing figures. Now that we'll see a larger and brighter Moon, we will have an excellent opportunity to discover hidden figures in the Moon geography.

One of the most recognizable silhouettes is one of a rabbit with long ears, so fascinating is the image that the Maya created a legend to explain what it was then, a mystery. The legend involves the god Quetzalcoatl who, before the act of generosity of a rabbit who offered to feed at a time of dire need, decided to submit to the moon in thanks.

Thus, the image of the rabbit would be seen by all and for eternity.

The keenest observers - Cleopatra and Abraham Lincoln among them said they saw a human face on the surface of the moon, and it was probably the same that inspired the famous sequence in the film "Le Voyage dans la Lune" (Voyage to the Moon), by pioneer French filmmaker George Meliés.
