NASA NASA's TESS Mission Hopes to Find Exoplanets Beyond Our Solar System

The worlds orbiting other stars are called “exoplanets,” and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. This rocky super-Earth is an illustration of the type of planets future telescopes, like NASA's TESS, hope to find outside our solar system. via NASA http://www.nasa.gov/image-feature/nasas-tess-mission-hopes-to-find-exoplanets-beyond-our-solar-system
