Researchers at the University of Montreal and the European Southern Observatory (ESO) discovered the first planet on record, the CFBDSIR2149 (interstellar planets are also known as stray planets because they are not subject to any star gravitationally).

While the existence of that move through space in a free-without turning around anything-existed only in theory, this planet is only 100 light years from our solar system in the stellar association AB Doradus , a group of about 30 young stars move through space and it was believed that there had only failed stars (best known as brown dwarfs )

Since there is no nearby star that interferes in the observations, scientists have investigated in great detail CFBDSIR2149. The planet has between 50 and 120 million years old, a temperature of 400° C and the mass of between four and seven times the size of Jupiter.
