"It's about seven light years," Guinan said.
This Super Earth has a mass of at least 3.2 times that of Earth, and it completes a revolution around the Barnard star in 233 days.
Its mass exceeds the earth about 3.2 times; the temperature on the surface of Barnard "s Star b – about -170 degrees Celsius:" makes the planet not a very good candidate to look for extraterrestrial life.
After 20 years of careful academic observation around one of the closest stars of the Earth, scientists now have reason to believe that there might be what has been described as a "super Earth" just six light years from our planet.
In an important discovery, a team of global astronomers led by Ignasi Ribas from the Catalonia Institute for Space Studies (IEEC) and the Space Science Institute (IEEC-CSIC) have found candidates for the planet orbiting the Barnard star. Subtle changes in data – the use of existing scientific instruments can be registered very accurately.
In the past there have been other attempts to identify planets orbiting Barnard's star but these experiments resulted in failure.
Despite the relative closeness of the Barnard Star (0.4 times the distance between the Earth and the Sun), the exoplanet receives little energy from its fading mother: only 2 percent of the Sun's supply for our Earth.
This breakthrough, announced in a paper published by the journal Nature, is part of the Red Point project and CARMENES, which previously helped find Proxima Centauri.
Exoplanet is very small and very far from its parent star has not been found before using the radial velocity technique.
However, because the Barnard Star is a red dwarf star, a small and cooled star that may be about two times older than the Sun, it produces relatively little light so it is difficult to distinguish every object in its orbit. This single star is closest to our own solar system.
Flashback: Exoplanet is the second best known space planet to Earth, CNN reported. "Follow-up observations have taken place at different observatories around the world". This sway affects the light coming from the star.
It may be cold, unfriendly and all but not visible but the new planet has one thing that happens for it: it's really close.
& # 39; Luckily, our old planet search program gave us the time we needed to collect enough precision radial speed data with HIRES to start feeling the existence of planets & # 39 ;.
