Yes, astronomers have discovered thousands of exoplanets, some of which are considered to be Earth-like in terms of their size, composition, and distance from their host stars. These exoplanets are located within the habitable zone of their stars, where conditions may be suitable for liquid water to exist on their surfaces. While we have not found an exact replica of Earth, the discovery of these Earth-like exoplanets suggests that there may be many more potentially habitable worlds in our galaxy. **

There is only one Earth in our solar system. It is the third planet from the Sun and the only known planet to support life. While scientists continue to search for exoplanets in other solar systems, as of now, Earth is the only known planet with the right conditions to sustain life as we know it. **
