The space is filled with planets rebels

Half a billion worlds roam the galaxy without being tied to a star, a new study.

The universe continues to show that other worlds are possible. They were first exoplanets orbiting stars outside our solar system, then the twin assumptions of the Earth and now, a world class untethered behave so strangely that there is no consensus to name them.

Planets are supposed to roam free in space, without turning a star like the Earth does and most of the more than 500 exoplanets confirmed since 1995. An international team today in Nature describes ten of these worlds, which have been called "planetary masses."

Are the size of Jupiter, the largest planet in the Solar System, and its distance to the nearest star is ten times greater than that between the Sun and the Earth (1,500 million kilometers). Therefore, the authors suggest that "most" of them "are not tied to a star."
