First photographed homeless wanderer planet that walks through the universe itself

This is not Nibiru, soothe scientists


Lonely Planet, the homeless are not gravitationally bound to any star, astronomers have captured a large international group, which carried out observations using telescopes in Hawaii and Chile (Canada-France-Hawaii Telescope and the European Southern Observatory's Very Large Telescope). Great body, located about 100 light-years from Earth, the designation CFBDSIR J214947.

Scientists estimated the age of the pilgrim in 120 million years. Quite young.

 
 

As stated by the researchers — astrophysicist Iten Artiga (Itienne Artigau) University of Montreal (University of Montreal), before astronomers assumed that planets may be homeless. But to fix one of these objects were the first.

Indeed, last year a prominent American ekzoplanetolog — Professor David Bennett of the University of Notre Dame — proves pilgrim is not fiction. And do not even exotic. Common in the universe and must be found. Like, there were space "homeless" do not by themselves, and wander off, because they were thrown from orbit their parent stars in the early stages of the formation of planetary systems.

Now found a planet larger than Jupiter CFBDSIR J214947, weighs in at about 4 times. But even away from the stars, space heaters, for some reason it is very hot — surface temperature of about 400 degrees Celsius.

Naturally, the details of the space "homeless" long fueled fears about the mythical planet Nibiru. Like, it was from her visit to the solar system, there was a terrible accident. Maybe even the end of the world, the expected December 21, 2012. Astronomers comfort: nothing CFBDSIR J214947 to Nibiru has not. It is very far away. Not even close.

On the other hand … Reasons to fear is still there. Once the pilgrim planets actually exist. Suddenly we, in fact, some of them flying? And astronomers until it just does not see? As seen before this most CFBDSIR J214947.

MEANWHILE

Closer to the sun the other star

Russian astronomer Vadim Bobylev of Main (Pulkovo) Observatory (Pulkovo) used data collected by the European research probe Hipparcos. Namely traffic information about 35000 nearest stars. Reconstruct their orbits, he calculated that the star Gliese 710 with a probability of 86 per cent fit very close to the solar system. And it is possible that even be in orbit of Pluto. True, this will not happen soon — after 1.45 million years.

The star Gliese 710 mass of 0.6 solar, located in the constellation of the Serpent, is still away at 63 light-years. But coming at a rate of several tens of kilometers per second.

— You can not say that one star crash into another, — explains astronomer. — This event is almost impossible. But during the convergence gravitational field passing stars can affect objects in the solar system. And cause cometary bombardment.

In other words, Gliese 710 is able to cut into the Oort cloud — a huge "storage" of billions of ice blocks, located beyond the orbit of Pluto. And to change the trajectory of many "sleeping" there facilities, increasing the likelihood of falling to the planets of the solar system. Including the Earth.

Studies also have shown that the last time we flew up pretty close white dwarf WD 0310-688 (HIP 14754). It happened 300,000 years ago.

For the past 2 million years to our world converged 9 stars. And tens of millions of years of their course, was much more. Some may have had a planet. Suddenly, among them were inhabited? Yes, and with a highly developed people, learn at interplanetary travel? Then our — suddenly close — brothers on reason could reach Earth. And this trip would not look weird — interstellar — flight, which the need for the speed of light.

For periodic convergence of other stars to the sun fuels the hypothesis that the so-called paleocontacts. The visits of aliens on the ancient Earth. It is possible that the primitive human ancestors had witnessed at least one of them. Two million years ago, humans were so reasonable, that produced the fire. A 300 thousand years lived and someone smarter.

Finds a star next visit — after 1.45 million years old — anyone in the world is not known. Even if a guest — Gliese 710 — will be habitable planets.

It is unlikely that there is any chance that flew in the Sun star will be captured and posted on its orbit. In the past, millions, or even billions of years, none of the guests did not stay in the new house.
