Detailed explanation-1: -The standard definition for a habitable planet is one that can sustain life for a significant period; based on our solar system, life requires liquid water, energy, and nutrients.
Detailed explanation-2: -Enceladus, along with Jupiter’s moons Europa, Callisto, and Ganymede, all hide massive global liquid-water oceans beneath their icy crusts. Having large amounts of liquid water available could be a huge support to a human colony.
Detailed explanation-3: -Simply put: Earth-like planets are not the only places where life could form. We know from our own solar system that icy moons orbiting giant planets far away from the Sun-such as Europa, Ganymede and Enceladus-can have underground, habitable oceans too.
Detailed explanation-4: -A special planet: the habitable Earth What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
Detailed explanation-5: -There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres.
