What conditions would need to be considered when terraforming a hypothetical super earth in the habitable zone of any of these celestial bodies? I’m curious because I’m currently thinking of building a binary star system in universe sandbox where life develops and evolves on two massive super earths that are roughly 3.00 and 4.00 earth masses with oceans, continents on both of them, and a mostly tropical climate that have been terraformed by an alien race from a small F-type star system and placed in the habitable zone of two of these celestial objects, I’m curious to know which of these celestial objects is the most promising to develop life in based on temperature, lifetime, and instability of these celestial objects.
