Moons closer to their planet than the habitable edge are uninhabitable. Terraforming machines were created and dispatched to terraform planets into habitable worlds. High multiplicity planet systems are much more likely to have habitable exoplanets. This is a list of potentially habitable exoplanets and possible exoplanets. This is so close that any habitable planets would be tidally locked. The chief assumption about habitable planets is that they are terrestrial. Kasting was the first to present a detailed model for the habitable zone for exoplanets. Kepler-186f and Kepler-442b, were likely the best candidates for being potentially habitable planets. Kepler-186f and Kepler-62f, were likely the best candidates for being potentially habitable planets. Disagreement exists about whether current technology could render the planet habitable. This would place it and any of its moons in the habitable zone. "Galactica" jumps away and arrives at a habitable planet. Several of them were nearly Earth-sized and located in the habitable zone. Current models predict billions of habitable worlds in our galaxy. A vast land rush begins now that portals to other habitable worlds have opened up.
