More than 1 billion is a credible estimate of the number of habitable planets, or NHPs, in our galaxy based on current scientific knowledge.
Out of the eight planets, three (Venus, Earth, and Mars) may be able to support life. One in five planets outside of our Solar System are thought to be capable of supporting life, according to recent findings of extrasolar planets: Planetary lifespan on average. Scientists estimate that the closest such planet may be 12 light-years away. There have been discovered 59 possible inhabited exoplanets as of June 2021. On K2-18b, an estimated 110 light years away super-Earth that may be habitable, water vapor has been found. The exoplanet was previously discovered by NASA's Kepler satellite in 2015, but data processing has uncovered new information that has never been seen on a super-Earth.
