It doesn't mean a … In another study, published September this year in the journal Astrobiology, German and American researchers identified 24 “superhabitable” worlds out of the more than 4,000 known exoplanets. A planet’s ability to harbor life results from the complex interplay between its host star, its own orbit and rotation, and the make-up of its surface and interior. This sweet spot is called the habitable zone, where life might be possible. These results suggest that the process of tidal locking is a major factor in the evolution of most of the potentially habitable exoplanets to be discovered in the near future. Out of more than a thousand exoplanets that NASA’s Kepler spacecraft has detected, only 12 have been found in the habitable zone of their stars and are smaller than twice the size of Earth, making Earth-like planets a rarity. Previous estimates about determining the number of potentially habitable exoplanets there are in our galaxy were heavily based on the planet’s distance from its star. If they be not inhabited, what a waste of space.” - Thomas Carlyle RAJEEV MISRA December 2017 Abstract Kepler detected exoplanets using something called the transit method.
