Part 3/15:
Kepler-22b isn’t just another exoplanet; it’s an anomaly that defies easy classification. Its size—about 2.4 times that of Earth—places it in the category of "super-Earths," worlds larger than Earth but smaller than ice giants like Neptune. Its composition, orbit, and potential habitability raise more questions than answers, making it a tantalizing puzzle for scientists.
Location and Orbit
Circle the star Kepler-22, a G-type star similar but slightly cooler than our Sun. Located in the constellation Cygnus, Kepler-22b’s light takes over six centuries to reach Earth, a reminder of the universe’s immense scale.
