Which is the second planet suitable for human habitation in the world? Can humans find such a planet?

This planet is located in an extension of a relatively cold galaxy, and its atmosphere is relatively warm, which just enables it to have liquid water. This planet is the first time that scientists claim to be absolutely sure to find it? A pleasant environment suitable for human migration? This planet is also the first terrestrial planet discovered outside the solar system. The universe is so vast, I believe that besides this planet, there must be many extraterrestrial planets suitable for us to live in, but we haven't found them yet. In the solar system, the earth is the only living planet known at present.

Although human beings have been searching for extraterrestrial life in recent years, hoping to find the first celestial body with life, it is also found that the existence of super earth increases the possibility of human migration. But most of the time, what do we see Super earth? It is far away from us. Although the current technology can give a preliminary estimate, there is no way to determine whether it is suitable for human habitation and whether there is life. According to the description of the astronauts who were lucky enough to fly into space, the earth they saw in space was a beautiful, crystal-clear and only living planet, surrounded by a thin layer of water-blue tulle.

The earth has been selflessly dedicated to mankind. However, because human beings don't know how to cherish, uncontrolled exploitation and random destruction not only make the natural resources of the earth less and less, but also cause a series of ecological disasters, which threaten human survival. For example, in July 1995, an incident happened in our country: several factories discharged excessive sewage and smoke into the ocean and atmosphere, which led to a large decline in acid rain and destroyed a large area of forests and crops. This not only pollutes the environment, but also causes serious losses to natural resources.

However, although we have found a planet that may be suitable for human habitation outside the earth, it is difficult to immigrate there according to our current scientific and technological level. Therefore, I think we should cherish our earth. After all, we were born and raised here. She was our first mother. Now scientists? Look around? Earth, with emphasis on Mars with a diameter of about 53% and a mass of about 1 1%. This is about to start digging humans? Second habitat? Or? The second earth? Yes Because humans may move to Mars in the future, and now scientists suspect that there is a high probability of extraterrestrial life on Mars, and even there may be life now, which greatly promotes our interest in Mars.
