Exoplanets: Crash Course Astronomy #27
Season 1
Episode 27
Phil explains that YES, there are other planets out there and astonomers have a lot of methods for detecting them. Nearly 2000 have been found so far. Exoplanets appear to orbit nearly every kind of star, and we've even found planets that are the same size as Earth. We think there may be many billions of Earth-like planets in our galaxy.
