The solar system is made up of many planets and each of them has different qualities. In this article I will tell you about the surprising Characteristics of the Planet Mercury .
14 Characteristics of the Planet Mercury
Mercury, closest planet to the sun planet with attractive features for science and astronomy lovers. Note the Characteristics of the Planet Mercury It may be a time-consuming task, but admiring its particularities up close is enchanting. Below is a list of the physical and chemical qualities of this portion of our solar system.
1. Smallest planet
One of the Characteristics of the Planet Mercury It is the smallest of ours solar system.
2. Body of Mercury
Being the body planetary Of those that make up the Solar System, Mercury has a diameter of 4.879 km, which makes it about three times smaller than Earth, which. It is also the planet located closest to the sun and is also the smallest of the eight planets of our solar system.
3. Constitution of Mercury
Another of them is its constitution; due to its great density, astronomers estimate that Mercury must have a large solid core, near which it melts there is a mantle about six hundred kilometers thick. Likewise, Mercury's surface is thought to be accessed mostly with iron. In the same way, scientists establish that the crust of this planet is about one hundred to two hundred kilometers thick.
4. Surface of Mercury
As for the surface of Mercury, astronomers have come to assimilate this planet with the Moon, because like this terrestrial satellite, Mercury's surface is full of holes, products of the perpetual crashes of meteorites against this planet, which have caused holes in this planet that wave from a few meters to hundreds of kilometers. In addition, the presence of a peak stands out on its surface, which is located in the center of the planet.
Likewise, on the surface of Mercury, it emphasizes the Caloris Basin, which achieves one thousand five hundred and fifty kilometers. Astronomers think that this basin is the imprint of a huge asteroid hit on Mercury, millions of years ago, in the early days of the Solar System.
5. Structure of Mercury
Mercury is a solid planet and rocky and has possibly been dormant for many years.
Its surface is, as it was named, very similar to that of the natural satellite of the Earth because it shows marks (craters) as a consequence of the impact with meteorites and comets. The craters vary in size, but highlight the so-called Caloris and Rachmaninoff, with 1,550 and 306 kilometers in diameter, proportionally, which were created due to the impact of asteroids at some point in the early history of the Solar System.
Similarly, there are smooth and notched areas as well as cliffs. Some of these alignments run for several hundred miles and are up to 1 mile high. The principle and nature of the rough ridges of the Caloris Basin not effective; Some scientists believe that they are tectonic in nature while others insinuate that they were created due to the volcanic flows that come out of the rocks.
Also, it enjoys a core metallic whose radius is about 2,000 kilometers. Recent explorations found certainty that this core is partly molten. On the other hand, the outer layer is about 400 kilometers thick.
6. It does not have a satellite
One of the most important that like the planet venus and Mercury, this planet does not have any satellite orbiting around it.
7. Mercury's atmosphere
La atmosphere of Mercury is strongly thin, that is why it is so easy for meteors and asteroids to reach the surface and hit it. Its “atmosphere” is actually an exosphere, it is mainly made up of hydrogen, oxygen, sodium, helium and potassium and founded by the effect of atoms separated from the surface and the impact of micrometeorites. Since the surface temperatures are usually very high, the atoms run quickly and comfortably into space.
8. Mercury Temperature
Due to the great proximity of this planet to the hot Star King, astronomers have calculated that the temperature can reach about 427 degrees Celsius in the day. Likewise, the thin atmosphere that this planet has means that the temperature cannot stagnate, so the nights are another scenario, in which temperatures of up to minus one hundred 69 degrees Celsius can be achieved.
Mercury, despite being the closest planet to Salt, is not the planet that shows the hottest temperatures. The hottest planet in the solar system is Venus, due to its opaque sulfuric acid atmosphere. However, Mercury, which almost completely lacks an atmosphere, does host the most extreme temperatures, ranging from -170°C at night to 430°C during the day.
Mercury's axis has the smallest current of all planets of the solar system, and this translates into a general lack of seasons or seasons.
9. Mercury Gravity
The planet Mercury has only 38% of the earth gravity. This represents that Mercury does not have the power to preserve the atmosphere in its area and is exposed to the different particles originating from the sun (wind solar). However, these particles can change the chemistry of surfaces and establish different gases, creating a small variety of atmosphere.
Likewise, this low gravity also prevents Mercury from having rings or moons. However, there are texts that stated that between Mercury and the sun, there was still another planet cited Vulcan. Today the existence of such a planet is ruled out, nor are there any theories that in the past it has been or has been swallowed by the enormous gravity of the sun.
10. Transit of Mercury by the Sun
Among other of the Characteristics of the Planet Mercury, is found to pass in front of the orbit of the sun, being seen from the Earth like an opaque organism boy. This astronomical phenomenon happens at least 13 times during a century, happening during the first twenty years of the 2003st century in 2006, 2016 and XNUMX.
11. Rotation of Mercury
However, the rotation phenomenon lasts almost twice as long as that of Planet Earth, occurring in a total of 58 days, with 16 hours, the time that Mercury used to turn around on its own axis.
12. Orbit and Translation of Mercury
Similarly, Mercury has the most fantastic orbit of the group of planets, known as minor planets, determined to be elliptical. Also, scientists have defined that Mercury takes a total of 88 Earth days to go around the sun being this time then the resemblance to what lasts a year on Mercury.
13. Distance from Mercury to the Sun
This planet is located at a distance of fifty-seven million, nine hundred and ten thousand kilometers (57.910.000 km), which makes it the closest planet to Earth. Astro the king, throughout the Solar System. Some astronomers have shown that it is assumed that from the surface of Mercury the sun would be observed three times larger than the dimension seen from Earth.
14. Double Dawn
According to what astronomers have recorded, the proximity of a phenomenon named "perihelion"determined by a slow period in Mercury's orbit near the sun, causes a phenomenon cited as Double Dawn to be located at defined points on the planet, in which the sun rises over the horizon, hides again at the same point, and immediately it comes out again to continue its celestial journey.
INTERESTING DATA: His pseudonym comes from the Roman god Mercury, messenger of the gods. If a person were to stand on Mercury at its closest point to the Sun, it would appear to be three times larger than it appears on Earth. Another interesting fact is that Mercury has a greater temperature diversification than other planets Of the solar system.
