More Clues That Earth-Like Exoplanets Are Indeed Earth-Like

Artist’s depiction of Kepler-62f. Image credit: NASA Ames/JPL-Caltech/T. Pyle Kepler-186f is the first identified Earth-sized planet outside the solar system orbiting a star in the habitable zone. This means it’s the proper distance from its host star for liquid water to pool on the surface. The Georgia Tech study used simulations to analyze and identify the exoplanet’s spin axis dynamics. Those dynamics determine how much a planet tilts on its axis and how that tilt angle evolves over time. Axial tilt contributes to seasons and climate because it affects how…
