The search for planets like Earth has always been a scientists’ area of interest. Most of the alien planet discoveries were made by the Kepler Space Telescope to help NASA find new Earth-like planets.
NASA has found a few planets similar to Earth. They are-
It lies just 22 light-years from Earth and is at least 4.5 times in size. However, the planet orbits around its host star in just 28 days and is located in the habitable zone.
This planet lies 600 light years away from us and is about 2.4 times its size. But, its orbit is around 290 days long.
This planet is about 40 percent larger and lies about 1,200 light-years away. Its 267-day orbit, however, puts Kepler-62f squarely within the habitable zone.
