Comment Actually, habitable is a reletive term (Score 1) 64
When talking about "habitability" in the context of Kepler Mission, it's more like "as much as Kepler can say about this object's Habitability".
It's not necessarily that the planet or the moon are within the so called habitable zone.
Since Kepler is able to analyze the atmosphere on some of the bigger objects, a planet within the habitable zone but with an invalid atmosphere or for example a gas giant would not be considered "habitable" by Kepler's standards. It also includes many other factors. Not just the location of the object within the habitable zone of its star.
