Interesting facts from life
What are we looking for?
The most interesting secrets of the Solar system.
0 The cosmos has attracted human consciousness since ancient times.
It seems that nothing else interests a person so much.
Today we will look at our well known Solar system.
The solar system is huge for every person, however, in comparison with the cosmos as a whole, it is just a grain of sand in a huge desert.
The planetary system consists of many celestial objects and a central part, the" heart " – the Sun.
Our planet contains eight planets: four small inner ones – Earth, Venus, Mercury and Mars, as well as four large outer ones – Uranus, Saturn, Neptune and Jupiter.
1. Everyone probably knows that Mercury is located closest to the surface of the Sun.
And, accordingly, most believe that it is the hottest planet in the system.
However, this is not the case.
The" hottest " was Venus.
It is located just behind Mercury.
Its average temperature is 475 degrees Celsius.
This mark is enough to melt lead and tin.
The maximum of Mercury is 426 degrees, which is an order of magnitude lower than the temperature of Venus.
But this is not the last fact, according to the criteria of which it is ahead of all the planets in the system.
Venus is also the brightest.
Everyone knows that planets do not glow by themselves, they only reflect the light of the Sun.
So in the atmosphere of Venus there are special clouds that reflect about 75% of the sunlight falling on them.
But that's not all!
The only planet that, unlike the others, rotates
counterclockwise, so is Venus.
So we can rightfully consider this "beauty" a champion in differences from other celestial bodies of our system.
2. It turns out that over the past couple of centuries, our Solar system has lost at least two planets: Pluto and Vulcan.
Pluto has relatively recently ceased to be considered a planet and was renamed a dwarf planet.
But humanity started talking about the possibility of the existence of the planet Vulcan about 150 years ago.
It was assumed that this celestial object is located in front of Mercury, right at the" foot " of the Sun.
But later observations still excluded it from the list of planets in the system.
3. The most important discovery of mankind about the Solar system was, of course, the assumption of Copernicus that the planets revolve around the Sun, and not our Earth.
But, unfortunately, he did not even hear a "thank you" for this discovery.
Moreover, his followers were announced
exiles, and D. Bruno was even burned at the stake as a heretic.
4. The planet Jupiter has the largest number of satellites.
Although, it turns out that until 2001, it was believed that another giant, Saturn, was the champion in this indicator.
However, over the past few years, scientists have discovered more than two dozen moons of Jupiter.
At the moment, it is known that he has 63 of them, while the "opponent" has only 60.
5. To some extent, our planet Earth is also unique.
It consists mainly of the following elements: oxygen, iron, silicon, sulfur, magnesium, calcium, nickel, aluminum, sodium.
All of them were found throughout the universe, but only in the form of "echoes", traces that overshadow the abundance of helium and hydrogen.
In this regard, we can conclude that the Earth is a clot of rare elements.
But, this,
of course, it does not speak about any special place of the planet in the universe.
6. Interesting fact!
It turns out that we live to some extent inside our huge luminary – the Sun.
In fact, its outer atmosphere extends much further than the visible surface.
We are orbiting within the solar liquefied atmosphere.
One of the proofs of this is the aurora borealis, which is a gust of solar internal wind.
7. The closest and most interesting planet for us is Mars.
It was named after the well known god of war.
The second name of this planet is Red, because iron oxide predominates in its soil, and it, in the literal sense of the word, has this color.
By and large, Earth scientists have underestimated the importance of Mars.
It turns out that in fact, many types of the first microbes that appeared on Earth first appeared on the surface of Mars, and only then, with the help of asteroids, came to us.
Scientists have also proved that there were a lot of water resources on the" Red " Planet in ancient times, which eventually disappeared.
Evidence of this is the dried riverbeds that encircle the planet, as well as many minerals that could only be formed with the help of water.
8. There is another celestial body that has been of interest to earthlings for several years.
This is our satellite the Moon.
However, strange things are happening around her.
During the Cold War, the USSR and the United States competed among themselves who would step on its surface faster.
The first person to visit the moon was still an American Neil Armstrong.
But later something strange happened, because since then scientists have sharply lost interest in the moon.
And Neil's interview with the statement that she is busy with another form of life, which earthlings are not able to resist, suggests that there is some secret that is carefully hidden from us.
It is more than obvious that some events have occurred on this celestial body, which are not told to humanity in order to avoid panic.
9. The solar system is filled not only with many planets, but also with various other cosmic elements, such as asteroids.
The largest cluster of them is located between Mars and Jupiter.
This space is commonly called the Asteroid Field.
In films about space, you can often see a picture of how spaceships maneuver between asteroids to avoid collisions, because there is a small distance between them.
However, this is not really the case.
There is a rather large distance between the asteroids, even in the above mentioned Field, which allows the ship to fly without much effort.
10. Another interesting cosmic mystery of the cosmos and the Solar system in particular is Dark matter.
Scientists suspect that it is of the greatest importance in the Universe, but they are not yet able to solve it.
It is well known that dark matter is a kind of anchor that holds galaxies together.
It turns out that by examining some facts, we can conclude that the Earth is also densely shrouded in dark matter.
This is possible because spacecraft mysteriously change their orbital velocity during their flight from the Earth and to the Earth.
But still, this is just indirect evidence and scientists cannot give an official statement yet.
Our Solar system is still a huge bundle of secrets that scientists have yet to discover.
After all, it is huge in comparison with our planet and does not end with Pluto, as we used to think.
It extends beyond our understanding for many thousands of light years.
However, in comparison with previous centuries, over the past few years, humanity has made a huge breakthrough in the study of the system.
We hope that these are not the last discoveries and in the future we will return to this topic again with new interesting facts.
