So what would life be like on a world similar to Earth, but which is merely a large moon around a huge gas giant? This digital painting explores that possibility. Here, we see a cold world, not unlike Earth during an ice age, orbiting its parent gas giant. Such worlds would have massive tides, impressive auroras, and regularly solar eclipses. The concept of day, night, and seasons would be different with an additional element introduced since not only does the moon rotate and go around the sun, but the moon goes around the parent gas giant as well. Worlds like this one almost surely exist - we have found gas giants large enough to theoretically have moons as massive as Earth - all that is needed is for them to have enough water and exist in the star's habitable zone.
