Comparative Habitability
In order to assess the likelihood of finding any sort of life on various planets and moons, Dirk Schulze-Makuch and other scientists have developed a Planetary Habitability Index which takes into account factors including characteristics of the surface and atmosphere, availability of energy, solvents and organic compounds. Using this index, based on data available in late 2011, the scientists found that Titan has the highest current habitability rating of any known world, other than Earth.

Famous quotes containing the word comparative:
“If you believe that a nation is really better off which achieves for a comparative few, those who are capable of attaining it, high culture, ease, opportunity, and that these few from their enlightenment should give what they consider best to those less favored, then you naturally belong to the Republican Party. But if you believe that people must struggle slowly to the light for themselves, then it seems to me that you are a Democrat.”
—Eleanor Roosevelt (18841962)
