Discovered planet without star “mother” close to the Solar System

Under the name of the planet is CFBDSIRJ2149 you see in the picture, the first planet without parent star closest to our solar system . A rogue planet orbiting without star, astronomers have confirmed the first known “free-floating”.

In the past there have been similar candidates, planets that formed in solar systems similar to ours that were thrown from the orbits of their host stars. In other cases, a so-called “failed stars”, commonly known as brown dwarfs. However, these candidates are extremely difficult to study, as nearby stars that are obscured when viewed by astronomers. In any case, the result is the same, failed to itemize or issue a formal opinion on the planet in question.

Until now. According to Philippe Delorme, author of the study:

The search for planets around their stars is similar to the study of a firefly sitting an inch away from a car headlight. The planet is found wandering near the free-floating object.

And is that Delorme and his team discovered while performing CFBDSIRJ2149 track and the night sky through Very Large Telescope in Chile. The researchers looked at hundreds of millions of stars and planets, finding only one CFBDSIRJ2149, homeless.

Once found and identified, astronomers have concluded that it is very close to our solar system, 100 light years from Earth, therefore, the closest to the “kind” ever discovered.

In terms of size, the researchers speak of a large planet, about 4.7 times the mass of Jupiter. In addition, the planet seems to belong to a group known celestial objects traveling as AB Doradus Moving Group. According to them, visible light CFBDSIRJ2149 be a planet deep dark red.

Finally, Delorme explains the significance of the find:

These objects are important because they may help us understand more about how the planets can be ejected from the planetary systems or how very bright objects can arise in the process of star formation. Our future studies should confirm CFBDSIRJ2149 as a free-floating planet. An object that could be used as a reference point for understanding the physics of similar are discovered by future special imaging systems.
