Tipping its hat to the possibility that aliens could have dramatically different biochemistry from earthlings, the index confines itself to measuring big-picture factors such as the presence of a solid surface, the average surface temperature, the strength of a planet’s magnetosphere (which helps shield it from cosmic radiation) and the like.
Unsurprisingly, Earth comes top of the list. Interestingly, though, Titan, a Saturnian moon covered in hydrocarbon lakes, takes the second spot in our solar system, ahead of Mars. And with a decent score too. Time to start packing?
