The first nomadic, "homeless" planet officially recognized as CFBSIR2149 has been discovered by researchers from the University of Montreal. Astrophysicists and astronomers have collected enough data to confirm and categorize this unique part of our solar system as well as determine evidence which theories related to the formation of other celestial bodies. The study found that CFBSIR2149 is approximately 50 to 120 million years old, has a mass four to seven times that of Jupiter, and has a temperature of 400 degrees Celsius.
In an official press release, astrophysicist Lison Malo stated: "This group is unique in that it is made up of around thirty stars that all have the same age, have the same composition, and that move together through space...It's the link between the plant and AB Doradus that enabled us to deduce its age and classify it as a planet." This dynamic discovery of "wandering" planets which do not orbit a star may shed some light on the collection of moving young stars known as the AB Doradus Moving Group as well as numerous other exoplanets.
Doctoral student Jonathan Gagne also confirmed in a statement that "Over the past few years, several objects of this type have been identified, but their existence could not be established without scientific confirmation of their age. Astronomers weren't sure whether to categorize them as planets or as brown dwarfs. Brown dwarfs are what we could call failed stars, as they never manage to initiate nuclear reactions in their centers."
Etienne Artigau also further elaborated with "This object was discovered during a scan that covered the equivalent of 1000 times the surface of the full moon. We observed hundreds of millions of stars and planets, but we only found one homeless planet in our neighborhood. Now we will be looking for them amongst an astronomical number of sources further afield. It's like looking for a single thread in amongst thousands of haystacks."
The discovery of CFBDSIR2149 offers astronomers and astrophysicists proof that though this is the first "isolated" planet to be gravity free, the likelihood that many more exist in numbers higher than initially predicted is greater than not.
