An online catalog showing 'at-a-glance extra-planetary planets that can be habitable' at a glance is ongoing

In order to solve various problems occurring on the earth such as global warming, population increase, food crisis, measures to "humans will migrate to planets other than the earth" may be advocated. It is impossible for mankind to head by spacecraft to planet outside the earth right now and start residing, but an online catalog that allows you to check extra solar system planets that may be possible in the future can be seen at a glance.

Many stars in the universe are observed, but most of them are stars that emit light themselves. On the other hand, the prediction that the extrasolar planets that do not emit light themselves "probably will exist" were among the researchers, but existence was not proven until the 1990's. After that, many planets outside the solar system have been discovered due to development of various observation methods and improvement of observation accuracy.

It is thought that some planets outside the solar system can reside in the same way as the earth as humans can. As a condition of a resident planet, it is necessary for the planet to revolve keeping a moderate distance from the fixed star and keep the temperature at which the water can exist on the surface of the planet. It is too cold for mankind to live if it is too far from a star, too hot it can not live.

The range of the distance from the fixed star suitable for the survival of life is called a habitable zone, and at the time of writing the article, a total of 55 extrasolar planets are said to be "in a habitable zone from a star" It is. Among them, there are one planet that is slightly smaller than the Earth, 22 planets that are about the same size as the Earth, and 32 planets that are larger than the Earth.

Among planetary extrasolar planets that can be habitable, it is a planet that is mainly an earth planet made of rocks and metals and is thought to have a high possibility of having water on the surface with just the distance from the fixed star This is the image arranged in order from the earth. Compared with Earth and Mars on the right side of the image, Neptune and Jupiter, we can see that both planets are larger than Mars and smaller than Neptune.

The nearest Proxima Centaur b is a planet that revolves around the Proxima Centauri , a red dwarf known as the nearest star from the sun, and the distance from the earth is 4 light years . The next closest Captain B is the planet of the CAPTAIN star , and the distance from the Earth is 13 light years.

Residable solar system planets which are not included in this image are not earth type planets or are in the habitable zone but the distance from the stars is too far or too close, the possibility that water can not be maintained on the surface It is said that it is high. However, it is included in extra solar system planets that can be settled as "it can not be said that there is no possibility of living in an optimistic sense."

In addition, I could see the figure of how far each planet is from a star in the list. Try clicking the diagram of Proxima · Centauri b ......

It shows how far from the star it is orbiting. It is turning around the dark green part even in the habitable zone and you can see how the planet seems to be kept at an appropriate temperature.

On another planet, although it passes through the habitable zone during revolution, it has a pattern that protrudes from the habitable zone because it is revolving depicting an ellipse shape ....

There was also a pattern that felt that it might be a little too hot, as we revolved inside of the habitable zone.

Just saying that these planets are "possibly habitable at the moment," you do not know whether you can actually live in or not by checking the environment of the planet in detail. However, just by looking at it, various fantasies came up and it became a catalog that can feel romance.
