Exploring Life Possibilities on Exoplanet Kepler-22b

Kepler-22b, an exoplanet 635 light-years away, lies in the habitable zone of a Sun-like star, offering potential for human life. Discovered using the transit method, it has a mass 36 times that of Earth and a year lasting 290 days. Despite its promising climate, challenges like extreme rotation and unknown gravity pose risks. Travel would require cryogenic sleep, and survival depends on adapting to possible high gravity and unknown surface conditions. Kepler-22b could be rocky, gaseous, or ocean-covered, each presenting unique challenges for habitation.
