The second closest exoplanet was discovered (just 6 light years from us)

They are constantly increasing exoplanets which are discovered in our neighborhood. An international scientific team has announced that it has found good evidence for its existence frozen an exoplanet that is at least three times as large as Earth and that moves near a nearby Barnard star, a mile away six years light from our own planet.

This is the second closest exoplanet to be discovered. In 2016, an exoplanet was discovered (by Proxima b) around the nearest Earth star Closeness his Centaur, about four light years from Earth. After the discovery of the new exoplanet, four planetary systems were found within ten light years of our Solar System and 14 planetary systems up to 15 light years away.

ABOUT Barnard's star – which is named after the American astronomer Edward Barnard, who discovered the star in 1916 – is the fourth closest to the Earth star after the threefold alpha Centaur astral system and seems to move faster than any other star in the sky.

This is the star of the red dwarf that appears in the constellation Ophiuchusa. It's smoother, shorter and older than the Sun, seven to ten billion years old, so it's much older than our Solar System.

The Barnard Biometric planet (or GJ 699 b) has a mass of at least 3.2 times the Earth, lasts 233 days (year) to remove the full trajectory around its star and receives only 2% of the radiation the Earth accepts from the sun. It is estimated that for this reason the average temperature on its surface is minus 150 to 170 degrees Celsius, so if the planet has water, it will be in the form of ice rather than wet. Thus the planet will be a frozen emptiness, inhospitable for a lifetime.

"We are over 99% sure that this planet exists," said lead researcher Ignasi Ribas of the Spanish Space Research Institute. Researchers have posted a relevant publication in the journal Nature.

According to AMPA, the planet will be the future target of next-generation telescopes, such as the NASA Wide Field Infra Red Survey Telescope (WFIRST).
