A new study on the habitability of Kepler 452b

The potential habitability of extrasolar planets is usually estimated by resorting to models that take into account the geological, chemical, climatic and astronomical parameters of the body under scrutiny. A new study of a group of researchers from the Astronomical Observatory in Trieste and CNR IGG has considered the habitability of Kepler 452b, one of the best candidates for a potentially habitable planet. Assuming a fundamentally rocky nature of this body, the results indicate that many parameter combinations lead to an at least partial habitability of Kepler 452b. However, only a limited set of parameter combinations assure that habitability can last for more than two billion years, assumed to be the minimum period of time allowing for the evolution of complex organisms able to produce biomarkers that are still observable today.
