If the earth is abandoned, will this planet be the next destination for mankind?

If the Earth is abandoned, will this planet named "KOI 5715.01" be the next destination of mankind?

The earth will eventually leave it.

Climate change and space disasters may make this day come earlier. When one day the earth is no longer suitable for human habitation, we will inevitably retreat. The question is where to retreat. If before, We can only look at space with intention and powerlessness, but since this is happening in the future, it is very likely that we can successfully leave this blue planet and find a place where we can immigrate. Scientists are working hard to find the vast world through detectors. A candidate "Earth" in the universe, just in case.

Led by Professor Dirk Schulz Marcucci of Washington State University, he formed a research team with astronomers from the Planck Institute for Solar System Research and Villanova University. The main goal of the research team is Identify the most potentially habitable exoplanets, which would need to be more habitable than Earth. The research team has drawn the outline of a super-habitable planet. What kind of planet can be called a super-habitable planet? The following criteria are required:

The planet needs to orbit a K-type orange dwarf star, because K-type orange dwarf stars are generally considered to be the most suitable star system for supporting life.

The age of the planet is approximately 5 billion to 8 billion years old.

It is 10% larger than the Earth, but the mass cannot exceed 1.5 times the mass of the Earth, and the radius cannot exceed 10% of the Earth.

The average temperature of the planet is 5°C higher than that of the Earth. The oxygen content in the atmosphere is between 25% and 30%, and the rest is mainly inert gases such as nitrogen.

In addition, there should be a larger terrestrial living space on the surface of this planet, with diverse habitats and terrains, scattered land, abundant water sources, and plate tectonics or similar geological processes.

The size of the satellite of this planet should be between 1% and 10% of the planet.

Have suitable magnetic field.

Based on this standard, the research team searched for qualified super habitable planets in the database of discovered exoplanets. They identified 24 planets among thousands of exoplanets that have or are basically habitable. Meet several of the above conditions. Although these are 24 planets, it is not certain that these planets must all be rocky planets. Due to the limitations of the current observation level, these confirmed planets may be Jupiter-like planets or ocean planets. Such planets are not suitable for humans. live. Of the 24 planets, 16 are in the right age range, five are in the right temperature range, and nine orbit the right type of star. Some of these planets only meet a few conditions, and only one planet meets all the above conditions (age conditions, temperature conditions, star conditions), which is the planet KOI 5715.01.

Some people are curious why there are only three conditions mentioned here, but not conditions such as oxygen content, geomagnetism, plate tectonics, terrestrial living space, and satellites. This is because the current scientific and technological conditions cannot be determined. these indicators.

In fact, among the extrasolar planets that astronomers have discovered, most of them are not conducive to the survival of life. Some of them may be Jupiter-like planets, some are not within the habitable zone of stars, and some There are no suitable conditions to sustain life. The telescopes we currently have can measure the type of star and the radius of the planet, calculate the orbit of the planet, and infer its mass. However, for more specific data about this planet, current telescopes are not yet able to provide it. Among these 24 planets, some are located more than 2,000 light-years away from us, and even the nearest planet is 100 light-years away from us. Although such a distance is like a natural chasm to us now, does this mean that such research is meaningless? I think not. This kind of research is to pave the way for the future, because humans will eventually leave the earth and go to another habitable planet. Perhaps this one named "KOI 5715.01" will be our next earth.
