Planet Mercury calls Earth or more than anything else calls us to know it at least from afar through the missions and studies of scientists and astronauts but also thanks to many legends which over time have been handed down and which concern this beautiful planet. Let's get to know its characteristics and also its fame.

Planet Mercury

Among the various peculiarities of this planet there is one that is very easy to remember and immediate to notice: it is the planet closest to the Sun. It is an objective fact not without consequences, the first of which lies in the fact that it is difficult to observe it. precisely because of this position. To date the planet is visible, very close to the Sun, only a little before sunrise or immediately after sunset, on very clear nights because in the rest of the time, it is obscured by sunlight.

Think that the planet Mercury is located just 58 million kilometers from the sun that if we think in terms of the Solar System it is very little, it is in fact just over a third of the Earth-Sun distance. We see other features of the planet, less easy to grasp with a single glance at a drawing.

The orbit that follows the planet is extremely elliptical, it appears almost squashed compared to that of other planets and Mercury only takes 88 days to travel it, it is a decidedly fast planet, the fastest to go around the Sun also for obvious reasons of distance. Almost to compensate, the rotational motion on itself it is very slow, it lasts 59 times longer than on Earth.

Planet Mercury: characteristics

There are planets, as we will see in other articles, that have satellites, the Earth itself has its own Moon, or that have rings, but the Planet Mercury it has none of that. It does not even have a real atmosphere, it is limited to being accompanied, enveloped, by a thin and quite dense layer of gas which, however, is not enough to shelter it from intense sunlight. It goes without saying that without the protection of an atmosphere like that of the Earth, on the Planet Mercury there can be no water on the planet because clearly the sun's rays would immediately evaporate it.

The absence of atmosphere for Mercury it is linked to its proximity to the Sun, yes, but above all to its very small mass. A "lightly heavy" planet exerts a force of gravity that is unable to hold around itself the gas particles that make up an atmosphere. Besides being the closest planet to the Sun, Mercury also enters the ranking of small planets, after Pluto, it is in fact the smallest planet in the Solar System.

From the measurements made, it would appear to be only one third of the Earth, the its diameter measures 4,878 kilometres and its mass is equal to 330 billion billion tons, 6% of that of the Earth. If we go to see how it is composed, we find in the Planet Mercury a large core of ferrous material which constitutes almost 80% of it, this core would seem to be a liquid core due to the enormous pressure carried out by the overlying layers.

Planet Mercury: temperature

There Mercury temperature during the sunstroke it can reach 420 ° C, while on the shady side it drops to 180 degrees below zero, a nice hike ends, no doubt about it. Let's see how this all happens. Because of his motion of rotation combined with that of revolution, a very strange thing happens on the planet Mercury. If we could walk on its surface we would see the sun rise in the morning, then drop briefly and finally rise again.

The same would apply to the evening: they would see the sun go down, rise a little in the sky and finally set. This is a theoretical reasoning but we will never be able to verify it because there can be no inhabitants on Mercury given its very high temperature, in the areas where the sun beats. It should also be noted that Mercury makes three rotations every two revolutions around the Sun, making two calculations so if we take any point on its surface we realize that it remains exposed to the sun's rays for 176 terrestrial days.

Planet Mercury: color

Let's see how it looks Mercury in the eyes of those who observe it even if from a distance. It may seem similar to the moon because of the many craters that cover it, there are many, both large and small, including huge cliffs. The largest craters have diameters of up to 200 km and are called basins, the most famous being the Caloris basin. There are also smaller craters from which the dust that covers the surface of the Planet Mercury.

Planet Mercury in astrology

Given its apparent fast movement across the sky, Mercury there is only 7.33 days left in each constellation of the zodiac. In astrology it is considered the dominant planet of the sign of Gemini and Virgo, it is the planet that represents communication, rationality, speed, cunning, intelligence and rapid learning. If we take a look at Chinese astrology we find that Mercury water dominates, one of the 5 essential elements together with wood, fire, earth and metal and which symbolizes life and purification.
