The astronomers found the closest to the Earth potentially habitable planet, Nature writes.
As an international group of astronomers published study states that the star Proxima Centauri, the nearest to our solar system, is an extrasolar planet Proxima b, which can be potentially suitable for life.
a team of astronomers from the European southern Observatory (ESO) discovered near-Earth exoplanet to Earth-like. Proxima Planet b is rotated around the nearest star to the Sun – the red dwarf Proxima Centauri, making a turnover of 11.2 days. Article about the discovery published in the journal Nature for August 25 its preprint available on the ESO website.
Proxima Planet b is 1.3 times the mass of Earth. Despite the fact that the object is located at a distance of about seven and a half million kilometers (0.05 astronomical units), it is located in the so-called habitable zone of a star – in orbit, where there may be water in a liquid phase
. According to Universe Today, astronomers announced the discovery at the beginning of the month, August 12 article appeared in zhurnaleDer Spiegel. August 22 was proanonsiroval press conference, and on Wednesday, August 24, scientists told the opening of the headquarters of the Observatory, based in Germany Garching.
Led by Guillem Anglada-PTE group of scientists suggested that a planet similar parameters located even closer, hardly exists
-. It’s not just the closest of the already discovered earth-like planets, but also probably the closest to us a planet outside the solar system from the already discovered or to be discovered. No stars, which is located closer to Proxima Centauri, to the solar system, planet, respectively, this star is located closest to the solar system – emphasizes Anglada-Escudo
This is a distance of 4.2 light-years from us. , whereas previously it was thought that the closest to our planet, circling around the red TRAPPIST-1 at a distance of 40 light years from the solar system.
on the “planet in the neighborhood,” it is known that it reaches 1.3 earth’s mass. Proxima B does turn around its star in 11.2 days. It is located at a distance from it significantly smaller than that between the Earth and the Sun (only 5% of the distance), but also the temperature of the star is also much lower.
On the planet may well be liquid water and the atmosphere. The air temperature on the surface is estimated at 30-40 degrees.
Unfortunately, most likely, and the level of ultraviolet radiation on this planet is 100 times stronger than on Earth. But even if the prospects for the people to the population of this planet is not actually science celestial body is still of great interest
-. Location next door – it’s not just a nice thing, it’s a dream come true for astronomers wishing to continue observation of the object, – says co-author Ansgar Reiners
