When it comes to planets, Earth is kinda teeny, even in our own solar system. And planets between the size of Earth and Neptune/Uranus can be found only in systems beyond our own. https://go.nasa.gov/3EaYJ3g #NASAExoplanets
Super-Earths – a class of planets unlike any in our solar system – are more massive than Earth yet lighter than ice giants like Neptune and Uranus, and can be made of gas, rock or a combination.
