Free from Pull

Astronomers have found a new class of planets that float freely in space. These were ejected from developing planetary systems and move around without being affected by the gravitational pull of any star.

Till now it was predicted that such planets exist. Now they have been discovered and could hold important information about planetary formation and evolution models. The 10 free-floating planets are thousands of light years in the direction of the central bulge of the Milky Way.
