Gliese 581 d is probably too large to be made only of rocky material, fellow astronomer and team member Stephane Udry said, adding it was possible the planet had a "large and deep" ocean.
"It is the first serious 'water-world' candidate," Udry said.
Plus this solar system is only 20.5 light years away from earth. A long term mission could actually be launched to this solar system and could get there in a single generation. In the meantime we could aim radio waves at this planet and see if we get any response.
