Habitability
editK2-296b is located in the habitable zone of the planetary system, meaning liquid water could exist on its surface. The planet is likely tidally locked to its parent star.[4] The Habitable Worlds Catalog, issued by the Planetary Habitability Laboratory, classes the planet as a warm superterran.[5]
