KOMPAS.com – International astronomers have found the planet around the sun.
Such a planet is the primary goal of searching for signs of life.
Barnard starred around the planet just six light years from Earth. The mass of the Earth is 3.2 times larger than Earth, it refers to the Super Land.
The magazine has published Super Earth Planet Reports Nature, today (15/15/2018) Guillem Anglada Escudé and its partners.

To whom BBC NewsAstrophysics at Queen Mary University, London, on Wednesday, 14/14/2018, claimed that this new planet could be the largest ever planet with a very large atmosphere. Planet may be rich in flying substances such as water, hydrogen and carbon dioxide that freeze on the surface.
The closest neighbor of the Sun.
As reported Science warningOn Wednesday, 14/14/2018, the star of the planet, called the orbital planet, is called Barnard Star.
This star is a red dwarf in space before our Solar System was born. It is only 6 light years away from Earth, the closest star of the Sun.
The red star is much smaller and cooler than the star, and Barnard's star is one of the quietest red clams.
Barnard star's condition is relatively light and proximity to the Earth makes it easier for astronomers to find exoplanet, one of which is planet Earth or Planet Star Barnard.
The letter "B" at the end of Planet Bintang Barnard B indicates that the planet is the first in the system. For example, later, other planets have been found in this system, perhaps called Barnard C. Star
BBC this planet turns into an orbit outside the so-called "snow line" that passes through the residential area where water can remain liquid in the surface of the water.
It is estimated at a certain distance that the surface of the planet can reach a temperature of -150 degrees Celsius. However, a great atmosphere allows the planet to warm up, making it a lifelong lifestyle.
Experts use the radial velocity method to detect them. This method can determine the star's moving nucleus under the influence of the gravitational force of the planet that has been orbit.
Nutrition also affects the star's light. As the light moves to the ground, the light shifts to the blue part of the spectrum and moves to the red when it flies away.
"This planet is very complex because the orbital period (the end of a orbit) is 233 days, and in a year you will see only a part of the cycle, and it will have to keep track of it for several years to ensure that these events are repeated," Escudy said.
For over 20 years, Esquige and her team had to revise data from two astronomical studies.
They also held a new competition with the Carmenes spectrometer in Spain, the Eso / Harps device in Chile and Harps-N instruments in the Canary Islands.
Radial speed technique was first used to determine this small planet from its parent's star.
"We can not get this conclusion from one experiment, so we need to combine some of the data carefully," said the astronomer at the University of Marmara in London.

In the future, when new generation telescopes emerge, experts hope to discover characters on the planet, including ambient-like thinning gases, such as oxygen and methane, which can be a sign of life.
"At present, the USA develops a small telescope for WFirst-cosmology. It looks like the picture of the planet is simpler and we can see different wavelengths in spectroscopy or optics, infrared, different colors, different substances in the atmosphere.
