Scientists discovered a second Earth, and NASA scientists found that the structure of this planet is very similar to Earth, with a similarity of up to 98%. Including the natural environment, the temperature and climate are very similar. On the surface of the planet, its hue is very similar to that of Earth. There are mountains, there is water, there is land, and there are even parts covered with greenery. Therefore, scientists speculate that there will be life on it.
The planet was named Kepler 452 b by scientists and also known by scientists as "Earth's Great Cousin" because it has a longer lifespan than Earth. It is 1.6 times the diameter of the Earth and more than 5 times the mass of the Earth. There is no doubt that its gravitational pull is greater than that of The Earth, about twice as much as the Earth. This means that if your weight is 50KG, then if you live on it, it is equivalent to carrying a 50 kg sandbag all the time.
The measurement data of the giant Kepler probe has brought astronomers years of research and analysis, including double detection, verification of real planetary data, and so on. As for the transit method, not only planets in orbit, but other factors can also reduce the brightness of stars, so astronomers need to do a lot of analysis to verify. For example, when the Kepler probe observes several binary star systems, the "transits" in the binary system are not real planets, but are easy to see.
Some friends might say that large space telescopes like Hubble can see objects tens of billions of light-years away. In fact, all of these telescopes can see the full picture of the giant celestial body. According to the pattern of formation and evolution of life on Earth, life exists only on planets, and we can see planets in other galaxies without forgetting. Even in the solar system, there is an elephant on Mars that is closest to our Earth, and Hubble has a hard time observing it.
Astronomer Vardan Adibekyan says that if you're lucky, there will be a planet around the sun's "twin." The planet is of the rocky type and is located in a habitable area. Finally, if the planet is contaminated with seeds of life from Earth, then the things people dream of are one, that is, "Earth 2.0" orbiting "Sun 2.0".
