10 amazing facts about the solar system
Makradar Technologies / / December 19, 2019
The scientific facts are a sham, and the obvious answer is wrong, when it comes to the solar system. The problem is that we know that we know nothing - and only now beginning to rediscover the world of planets around them. But it is not all bad: at least you can be confident in the ten facts.
Mercury is not the hottest planet
Although common sense suggests that the closer to the Sun, the warmer. But take into account would have cost and other factors, among them - the density of the atmosphere of planets. For example, Mercury is virtually non-existent. Therefore, there is no layer which would have kept the temperature at a high level of the planet. On the other hand, followed by Mercury, Venus goes. The second planet from the Sun, the atmosphere is very dense - a hundred times denser than Earth's. Here it is and serves as a kind of "blanket": covers the whole Venus and keeps it cool. Mercury surface temperature - 427 degrees, and Venus - 464.
US larger than Pluto
From edge to edge of the United States of America - 4700 kilometers. For Pluto same, this value is only 2,300 kilometers. In fact, the width of the dwarf planet - only a small part of the width of one of the Earth countries. Anyway, Pluto is so small that the recent debate about the time that a planet or not, is almost extinguished.
In space, there are no volcanoes
But there is a fountain. We, of course, a little exaggerated, but the essence remains the same. If on earth eruption involves the emission of lava, we understand what is meant by a red-hot liquid, consisting of minerals. The same things and with the magma - it only has saturated gases. But if we talk about the volcanic eruption on Io, for example, there is on the surface of the water with a lot of sulfur. On one of moons Saturn Enceladus from volcanoes sees water with gas impurities. There are kriovulkany - from their vents out the ice. Therefore, technically, most volcanoes of the solar system - is amazing fountains in which water is mixed with the occasional red-hot magma.
The solar system does not end with Pluto
If you have children - urgently reach for a textbook on astronomy and correct illustration. Edge need to draw much, much farther dwarf planet. It is believed that our system extends over a distance of 50,000 astronomical units from the sun. Beyond Pluto still lurk trans-Neptunian objects, and Kuiper Belt.
In the solar system is the tail
Most of all it is similar to the tail of the comet, with the difference that it is shaped like a four-leaf clover. It is called "gelioteyl". About him nothing was known for the simple reason that the tail is made up of invisible particles for traditional instruments. Gelioteyl stretches over 13 billion kilometers from the edge of the solar system. Thus the particles are scattered in all directions at a speed of 1.6 millionov km / h. This happens because of the strong winds.
On Earth, there are rocks from Mars
And it's not that we have brought them here. A detailed study of comets that fell in Antarctica and the Sahara Desert, has shown that it seems, these celestial bodies originally formed on Mars. Analysis revealed a material gas, which is indistinguishable from the atmosphere of Mars. Perhaps these comets were once part of the red planet, or were the result of a volcanic eruption, and only later flew to Earth.
The biggest is the sea on Jupiter
It was here that a huge amount of stored hydrogen and helium - the planet is composed almost exclusively of them. Assessing the mass and composition of Jupiter, researchers were able to assume that the clouds of ice is packed from the liquid hydrogen. Apparently, it is not only the largest in the solar system, but also the deepest. Approximate calculations indicate that the depth of the sea is about 40 000 kilometers - that is the same as the Earth's equator and the length.
One planet is not enough
Scientists noticed: they analyzed the orbits of the gas giants, and realized that they do not coincide with the majority of existing models. According to researchers, this suggests that the solar system was another planet, and its weight was a few tens of times larger than the Earth. This putative planet called Silence. It is believed that it was thrown into space and now she continues to move there. But if Tycho was in place, we would have it still not seen. It would have been far beyond Pluto, and one of its revolution around the sun would take millions of years.
Uranus and Pluto are diamond rains
Such conclusion was made by astronomers to learn about what these planets are vast oceans of liquid carbon. Research and calculations have shown that the carbon "waves" small floating diamond "icebergs." In addition, because of the physical processes of the planets should go and carbon rain. So there may well be precipitation in the form of tiny diamonds.
In fact, we live in the Sun
Of course, we usually imagine the star like a giant glowing ball that is out there and gives us the ability to get up and go to work that morning. However, it should reconsider its attitude to the sun. After all he has and the outer shell, which extends far beyond our planet. Each flash of the bright star provokes the northern lights on Earth, Jupiter, Saturn, Uranus and Neptune. Therefore, scientists believe that we are living in the heliosphere - and its radius is about 100 astronomical units.
