With the help of "Very large telescope" and telescope "Canada-France-Hawaii" the European southern Observatory has revealed the body, which is likely to be a planet, restless wandering in interstellar space. Today it is the most prominent candidate for this title and, by the way, the closest to us: to him about 100 light-years. Such a small distance and the lack of bright stars in the vicinity of the planet will allow specialists to get important information about its characteristics.

Several possible wandering planets, but the situation is complicated by the fact that we do not know their age. Astronomers cannot be sure that this is not the brown dwarfs, that is "failed stars, are not collected the mass necessary to trigger the appropriate reactions.

Object CFBDSIR2149, apparently, is part of a moving group of stars AB Golden Fish. This is the nearest to us such education. Most likely, these lights were formed at the same time. If the object is indeed associated with them (and, consequently, the young), it is possible to learn a lot of interesting. The researchers suggest that the body mass in 4-7 times the mass of Jupiter, the effective temperature is about 430 C. Age - somewhere 50-120 million years.

Statistical analysis of its own motion (visible change position in the sky) gives 87 percent probability that the object is associated with a moving group AB Golden Fish, and more than 95 percent probability that he was young enough to have a planetary mass. In other words, it is likely planet outcast, not little "nevesta". At a very young star clusters like the body was found, but they are too far and cannot be studied in detail.

By the way, this is the first stand-alone object planetary masses associated (probably) with a moving group of stars.

By the way, no matter how formed wandering objects like CFBDSIR2149 - in plain planets, which for some reason are departing from their systems, or brown dwarfs. They are interesting in any case. There is an opinion that such a body as large as a normal star.

The study is published in the journal Astronomy & Astrophysics.
