The super-ground class exoplanet that is Barnard's star break (the nearest single star to the Sun, the fastest moving star in the night's air) is called and a six-year-old light away is called Star Barnard & Sons (star b Barnard), writing Chronicle.info refers to Telegraph.
Its mass is about 3.2 times the ground; Starard Barnard surface temperature – – about -170 degrees Celsius: this means that the planet is not a very good candidate for searching for extraterrestrial life.
An international team of exoplanet scientists discovered an extensive range of data collected by seven advanced instruments (including the HARPS spectrumgraph South Europe Observatory) on telescopes in different parts of the world and consisting of 20 years of observations.
The researchers were looking for the slightest changes in the spectrum of spectrum of star, which could identify variations in its disaster caused by serious rocket planet severity. Subtle data changes – – using existing scientific equipment – – they can be registered with great accuracy.
"After a very thorough analysis, we are 99 percent sure the planet is really there, – – Ignaci Ribas's leading research scientist notes. – – However, we will continue to observe the star that moves rapidly to ban natural, but unlikely, in natural brightness, which could be mistaken for those caused by the planet. "
Barnard's star is the second exoplanet closest to the Sun. The first is Proxima Centauri b, which turns around Proxima Centauri and is about four years light away. Seren Barnard covers the star parent for 233 days, not a distance of it, equipping only 0.4 per cent of the distance separating the Earth and # 39; r Haul.

Despite this, the exoplanet receives only two percent of the energy received by our planet from the Sun: this difference is because of the fact that Barnard star (like Proxima Centauri) – – Red (compared to stars such as our Sun, red soul is relatively small and cold luminaries). Scientists have previously stated that the concentration of oxygen in very saline waters under Mars's surface may be high enough for aerobic microorganisms to exist there.
