No Little Green Men On Earth-Sized Exoplanet

Earth like objects are unique. We consider them to float around their sun. Now, the biggest free-floting or rogue planets appeares to have been huge -  ”40 times the mass of Jupiter (one Jupiter is equivalent to about 300 Earths).”

 A discover, reported recently in the Astrophysical Journal Letters, may mark the smallest rogue planet ever detected, and it could help prove a long-standing cosmic theory.. According to the study authors, this little world could be the first real evidence that free-floating, Earth-sized planets may be some of the most common objects in the galaxy.

We would not like to see little green men on the planet, as have to be created.
