Sister Earth, found in the nearest star, was so-so – TVNZ

According to rumors and reliably

Rumors that the astronomers of the European Southern Observatory (European Southern Observatory – ESO) discovered a Proxima Centauri – the nearest star to the Sun – a planet similar to Earth, confirmed. Scientists posekretnichat few days, fueling interest in his discovery, and August 24, 2016 reported about it at a press conference held at the head observatory office under the Munich , released the corresponding press release titled Planet Found in Habitable Zone Around Nearest Star. August 25, 2016 the results of the study appeared in the journal Nature:. A terrestrial planet candidate in a temperate orbit around Proxima Centauri

As one of the leaders of a huge research team Guillaume Anglada- Escudo (Guillem Anglada-Escude) from Queen Mary University in London (Queen Mary University of London, London, UK), there is no doubt: the planet is really exist. The chances that the astronomers were wrong -. A 10 million

For the opening of astronomers assembled press conference

what is the closest star to the Sun is not alone, was able to learn mainly through the instrument HARPS (High Accuracy Radial velocity Planet Searcher) – precision seeker of planets, as it is called. The device detects them, catching the stars shake caused by the gravitational influence of being in its orbit objects. Trembling and Proxima Centauri – astronomers few months followed its fluctuations, we rechecked the data. In the end, it turned out, the star of “rushes” in one direction and then in the opposite direction at a speed of 5 kilometers per hour. The calculations turned out that bothers her is only one planet, called Proxima b.

Tremors Proxima Centauri has given that it has a planet . – Proxima b

Under the light of the star called Proxima

Further calculations showed: Proxima b – rocky , Earth-like planets. It is only 30 percent heavier than ours, but in diameter, they do not differ. Proxima b rotates in a circular orbit, making one revolution in 11.2 earth days – that is, a year there lasts less than our two weeks. This is what the planet is very close to its star Proxima Centauri – is about 20 times closer than Earth is to the Sun

system Alpha Tsetavra- closest to us. Prior to her a little more than 4 light years. The system of three stars – the Alpha Centauri A, Alpha Centauri B and Proxima Centauri

Even before the details became known, and journalists, and even some experts. We are anticipating something sensational. Like, astronomers discovered the Earth’s twin sister. And even better it – with the conditions even more livable than us. Maybe life itself there noticed just so secretive. But expectations do not seem justified

Proxima b really is in the habitable zone -. Ie, located at a distance from its star, which is not very hot, and very very cold. And where the water may be present in liquid form. But the ideal local conditions is difficult to call. On earth, as it turned out, after all, much nicer

Proxima Centauri (α Centauri C, GL 551, the HIP 70890) -. The red dwarf with a diameter slightly larger than our Jupiter . Light the star gives just 0.15 per cent of the sun. It weighs about 10 times smaller than the sun. But the planet is discovered – Proxima b – is very close to its red dwarf. It is about 7.5 million kilometers away. Therefore, heat that the planet receives from the dwarf – it is 66 percent of what gives us our sun is enough to warm up, but do not overheat

<. p class = "title"> The zone of habitability, which is Proxima b, is closer to the parent star (right).

Two stars in the Alpha Centauri system – A and B – are similar to our Sun and the characteristics and size. Proxima Centauri – a red dwarf

Proxima Centauri is much smaller than our sun, but. Proxima b in the sky, it will look like a huge ball at the expense of the planet is closer to its star.

But what the temperature on the surface of Proxima b, is not known. There are only estimations, which give a large spread.

Scientists are considering two options. One – if the planet rotates, the other – if turned to one side of the luminary. In the first case, the temperature at the equator may be slightly above zero, the second – on the shadow side can be down to minus 90 degrees Celsius, solar – more than 30 degrees. That is, in general, is not a paradise.

Chance of temperature on the surface of Proxima b, if the planet rotates.

Chance of temperature on the surface of Proxima b, if the planet obrschena to the luminary one side.

is it possible to Proxima b at least some lives? Theoretically – yes. But there’s actually – find out is not yet possible. It is not known whether the Proxima b protective magnetic field – like the Earth. It is therefore quite justified fears that powerful flares that “famous” red dwarfs have long blown planet’s atmosphere along with water – even if they were there. And would not blow away. How to assure scientists, both options are open

Proxima b about a billion years older than the Earth -. Time on the origin of life was missing. Until reasonable. But if she was born? I preserved it? I hope this is not enough. Lived there would highly aliens, would long ago have arrived to us. We are there going to

On Proxima b sky you can see three of the sun -. One large and two small

still, the discovery of astronomers, no matter what, epoch-making. Proxima b is within human reach – up to her a little more than 4 Light s. Sometime you can even fly. And it leaves the chances to directly detect Proxima b life. And this can be remotely happen much earlier – with the help of a new generation of telescopes. Their already erect. And here and there was a goal – in short, we have a star named Proksima.P {margin-bottom: 0.21cm; }
