The Milky Way contains at least 100 billion planets according to survey

Abstract

Through detailed statistical analysis based on the detection of three exoplanets via microlensing, this study concludes that the Milky Way galaxy contains a minimum of 100 billion planets, each with an average of one per star. The work indicates a prevalence of Earth-sized planets over larger ones, with low-mass planets being more common. The study’s findings support other planet detection techniques and are significant for investigations into habitable planets. – AI-generated abstract.
