Default 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. "

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.

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.
