Astronomers at NASA have discovered an Earth-like planet more than Kepler-452b and 'a gold mine for scientific research'.
Thanks to the Spitzer space telescope, scientists have confirmed the existence of the planet HD-219134b, located about 21 light-years from Earth, much closer to Earth than the 1,400-year gap. light from Earth to Kepler-452b.

Although this distance is said to be very close, compared to Kepler-452b, human arrival in HD-219134b is still considered 'impossible' because it takes 387,000 years for the New Horizon spacecraft to speed up. The most current is 58,000 km / h that can reach HD-219134b.
In addition, although the Earth more like Kepler-425b, HD-219134b is too close to its star, the surface of this planet is very hot and cannot survive on it.
Planet HD-219134b cannot see directly even when using telescopes from Earth, however, the star of this planet can easily be seen with the naked eye and is located in the constellation Heavenly stars. North Pole.
Even so, the 'close' distance from the planet HD-219134b to Earth is expected to greatly support scientists who want to study the planet with space telescopes.
Initial observations show that HD-219134b is about 4.5 times heavier than Earth, about 1.6 times bigger than the Earth and only takes 3 days to spin around its star. In addition, the planet is thought to have a jagged surface like Earth, but does not have ice and gas.
Spitzer scientist Michael Werner said: ' This planet will be the most thoroughly studied planet in the last decade'.
This is because: ' Planets flying through their stars are' precious than gold 'planets because they can provide a lot of information for research'.
Accordingly, tracking this planet as it passes through its star, scientists can track the change of light that reflects chemicals that exist on the planet.
In addition, the planet is considered to be the perfect observed object from the James Webb telescope, expected to be launched into space in 2018.
The James Webb Space Telescope is a telescope that stands out among the latest generation space telescopes today and is expected to replace the Hubble space telescope.
The James Webb Space Telescope is capable of observing planets and objects far away from Earth with unprecedented details ever./.
