Modelling various types of Water-based Super-Earths
Water Planets
"CfA astronomer Dimitar Sasselov, together with two of his colleagues, have begun the pioneering task of modeling the interiors of super-earths. They address in particular the class of objects rich in water. They define a "water planet" as any super-earth whose mass is more than 10% water, whose core is made of silicates or metals, and whose surface layer is lacking in significant amounts of gas. They model nine possible water planets with a range of masses and water contents (up to 50%), and study the near-surface layer for icy or ocean-like properties.

"http://www.physorg.com/news183389336.html They probably know that sustainable life for the human species is becoming limited here on Earth, whereas it's just a matter of time before there's simply no good options for continually sticking it out (often fighting tooth and nail) here on Earth, especially when there are better off-world options. Even the planet Venus has impressive considerations that are being intentionally banished from public review, not to mention the interior of our moon(Selene) might not be too depressing. ~ BG |

You've just stated the obvious purpose of exploring space, to find somewhere to live. It won't be Venus, there might be a few settlements on the Moon, simply for its proximity though. Yousuf Khan |
