NASA (North American Space Agency) found the most old cousin of our
planet, with age and very similar structure, the official name is Kepler 452-b, but it has been dubbed Earth 2.0.
It is a little longer and older than our planet, as the Earth has more than 4.5 billion years, the Earth 2.0 has 6 billion, Kepler-452b is about 60% larger than the Earth and needs 385 days to complete one orbit around its star, Kepler 452.
The planet is in the constellation Cygnus, and its solar system is 1400 light years away from ours.
Still may not know exactly what it’s made her solo, but know that it is rocky and quite likely that there is water.
The discovery of Kepler-452b is important, but it is not unprecedented. Last year, US space agency’s astronomers found the first exoplanet with a size similar to that of Earth, the Kepler-186F, as the Earth 2.0 is also a “habitable” zone of a star.
Launched in 2009, the Kepler spacecraft has given the astronomer’s name (Johannes Kepler) to this planet, have been seen almost 4696 candidates for exoplanets while only 1030 have had their existence confirmed.
Is the question we are still alone in this immense darkness of the universe?
