Thousands of Planets are Known, but none are yet Identified as Earth-Like
Non-Kepler exoplanet discoveries (Left) are plotted as mass versus orbital period, colored according to the detection technique. A simplified mass–radius relation is used to transform planetary mass to radius (Right), and the >3,500 Kepler discoveries (yellow) are added for comparison. Eighty-six percent of the non-Kepler discoveries are larger than Neptune, whereas the inverse is true of the Kepler discoveries: 85% are smaller than Neptune.

Observing an exoplanet in the glare of its host sun-like star requires starlight suppression to 10-10,
Telescopes in space, above the blurring effects of Earth’s atmosphere are needed
A large aperture telescope separates the planet and star, and provides collecting area
