There are some calculations which suggest that the Milky Way is home on an average between 800 billion and 3.2 trillion planets, but there are some experts who believe the number could be as high as eight trillion.Furthermore, if we take a look at what NASA has to say, well find out how the space agency believes there are at least 1,500 planets located within 50 light years from Earth. These conclusions are based on observations taken over a period of six years by the PLANET—Probing Lensing Anomalies NETwork—collaboration, founded in 1995. The study concluded that there are way more Earth-sized planets than Jupiter-sized worlds.
