The Earth - our home planet, is the only planet in our solar system where life exists. There is no other planet like our earth in our solar system where life exists. But discovering true alien earth is hold the dream of astronomer and scientist. According to recent discoveries, the day is very near when this dream of astronomers will be fulfilled.
The scientist has so far discovered 2000 alien planets whose size, atmosphere, is quite similar to our Earth. In 1995, the first planet was discovered, which was orbiting a star like Sun. More than half of the discoveries were made by NASA's Kappler Space Telescope, which was launched in 2009 to find an Earth-like planet in our Milky Way Galaxy.
According to the Kepler Observation, in our Milky War Galaxy, many small, rocky worlds are like our Earth, and life is possible on many of them.
In April 2014, the Habitable Exoplanet catalog gave 21 such planets, which are beyond our Milky Way Galaxy, which is supposed to be life. These are not the same planets that are expected to have life, while there is still a lot of planets to discover, which can have life. But the catalog gave astrobiologists a new hope that life is possible on a planet other than our earth
We have described 10 such planets, where there is more chance of alien life.
Kepler-186f
Kepler-186f is the first Earth-Size Planet, which is in the habitable zone of its host star. It is 9090 light-years away from our earth. It is only 10 percent bigger than our Earth and it is a Rocky Planet.
Kepler-452b
This is an exoplanet that is doing orbit of a star like our Sun Kepler-452, it is 1,402 light-years away from our Earth. It was discovered by NASA's Kepler space telescope, which was shared by NASA on 23 July 2015 in front of the world. It is not known that this is a Rocky Planet, but based on its small radius, it can be called Rocky Planet. And it is not clear whether Kepler-852B has Habitabale Environment or not.
TOI 700 d
NASA's Transiting Exoplanet Survey Satellite (TESS) discovered a planet of the size of Earth present in its star's habitable zone that is 100 light-years away from our earth. Its distance from its star, make its surface suitable for the presence of water
The scientist confirmed this discovery by NASA's Spitzer Space Telescope. Its distance from the earth is about 100 light-years away. This is the first Planet of the Earth-size that is present in the habitable zone. Its mass is about 40% of the sun.
Kepler-1649c
Kepler-1649 is most similar to our earth in Size and temperature. Kepler-1649c is 1.06 times larger than our Earth, and it receives about 75% of its hearing light. It is 300 light-year far from our earth. Kepler-1649c has discovered through NASA’ Kepler telescope reanalyzed data.Kepler-1649c orbiting in its star habitable zone, the zone where a rocky planet supports liquid water on its surface.
HD 40307g
The HD 40307g orbiting the habitable zone of its parent star. Its distance from its sun is 54 million miles ( 90 million kilometers ), which is exactly half the distance of our sun and earth. Its distance from earth is 42 light-years.
Key word
Habitable zone
- The suitable distance of the planet from its star makes the planet suitable for life.
