While the most known planets have a star around which they turn, a single planet travels lonely in the space. This planet is 130 light-years away from the Earth and the distance is considered as comparatively close, so it gives the opportunity to be studied. The scientists gave her number instead of a name – CFBDSIR2149. The object is classified as “rogue planet” (known also as “nomad planet”, “free-floating planet” and “orphan planet”) which means a planet that was ejected from its star system or it never was a part of such system, and has a free orbit in the galaxy. Many scientists believe that some of the free-floating planets are formed in a way similar to the stars.
It is considered that the mass of CFBDSIR2149 is 4 to 7 times the mass of Jupiter and it probably resides near a group of young stars called AB Doradus Moving Group. The age of this group is between 50 and 120 million years and this gives the ground to consider that CFBDSIR2149 has the same age.
This object was discovered by its infrared signature from a team led by Philippe Delorme while he searched for brown dwarves (considered as “failed stars” and too massive for planets).
