Where does the earth come from? This is a lingering problem in people’s minds, and scientists have also conducted in-depth research on it. More than 4 billion years ago, the sun appeared in the nebula, and then the earth, Jupiter, Mars and other stars appeared one after another. Gradually, a huge solar system family came into being. The whole solar system is located in the habitable zone, and the earth is the only living planet in the solar system. Today’s earth is more and more fragile. People try to find a more livable planet, but the result is not ideal. Is there really an earth in this world? A long time ago, there were “three earths” in the solar system. Compared with the other two “planets”, the earth we live on is more lucky to stay. So where are the other two planets?
What are the other two planets and what disasters have they experienced?
With the continuous development of science and technology, scientists in the exploration of the starry sky believe that the “three earths” in the solar system, in addition to the earth we live in now, the other two planets are Mars and Venus. Originally, Mars and Venus were in the same habitable zone as the earth, but later the two planets were not so lucky as the earth. One became a “fireball” and the other became a “sand ball”.
The picture shows Venus
Venus surface temperature as high as 400 degrees Celsius, has become a veritable “fireball”
Among the planets in the solar system, Venus is a veritable “fireball” and a veritable “disaster planet”, because experts have found that the average surface temperature of Venus has reached more than 400 degrees centigrade, and the atmosphere of Venus is full of harmful gases such as sulfur dioxide and carbon dioxide. If it is normal rain under the earth, it will be in Venus from time to time Under the sulfuric acid rain, it can be seen that Venus is a very terrible planet, full of many dangerous factors. Is that what Venus is? No, relevant scientists think that long ago, Venus was not like this. Its surface temperature is very close to that of the earth. It is a very livable planet. Unfortunately, Venus suffered a large-scale volcanic eruption, and its natural environment began to show abnormal changes. Venus’s climate began to become very dry. With the surface temperature of more than 400 degrees Celsius, it is still a planet that no one dares to approach.
The picture shows Mars
Mars’s magnetic field disappears, annual storms become “sand ball”
Scientists have not given up on Mars for a long time. In constant exploration, in fact, about 1 billion years ago, Mars, like Venus, had a climate very suitable for human habitation. At that time, Mars was born at the same time as the earth. However, Mars was not so lucky in the future. After a huge asteroid collided with Mars, it left a special impression This crater is as big as Mount Everest. The vulnerable Martian magnetic field will disappear forever. Later, it will be unable to stop the solar storm and become a desolate “sand ball”. In the research, scientists found that there are still five very large basins on Mars, each of which is caused by asteroid impact. In the research data, scientists found that there will be a planetary impact on Mars every few thousand years. However, unlike Venus, Mars also has water and ice, but its climate is very dry and cold, and it is very cold all year round. Because Mars has no magnetic field and has been exposed to space, its radiation intensity is very high. It is only suitable for human beings to stay for a short time, not for long-term residence.
From the introduction of Mars and Venus, we can see that the planets in the solar system are very fragile. If there is a slight error, the whole planet will be doomed. But what is more terrible is that there is only one earth. Once the earth’s magnetic field disappears, or the planets collide, the consequences will be really unimaginable.
