Required to Leave Earth: Where to go?

American spacecraft have largely provided an unique remote sensing survey of a very significant moons among the plants in our solar system. Missions are now ongoing to major asteroids and far flung Pluto. But should you desire to do a quick survey look at the video Alien Moons. You might find a second choice to Earth if required to depart to a new world, and that is exactly what one professor has studied.

The University of Puerto Rico at Arecibo has provided a quantitative evaluation of habitability to identify the potential habitats in our solar system if humans were forced to leave the Earth. It is known as the "Quantitative Habitability Theory" (QH theory).

"Interestingly, Enceladus resulted as the object with the highest subsurface habitability in the solar system, but too deep for direct exploration. Mars and Europa resulted as the best compromise between habitability and accessibility, " says biophysicist Abel Mendez who produced the study of alien moon world human habitability as reported in Universe Today.
