Scientists have discovered over 6,000 planets that orbit stars other than our sun, known as exoplanets. More than half of these planets were discovered thanks to data from NASA's retired Kepler mission and NASA's current TESS (Transiting Exoplanet Survey Satellite) mission. However, the enormous treasure trove of data from these missions still contains many yet-to-be-discovered planets. All of the data from both missions is publicly available in NASA archives, and many teams around the world have used that data to find new planets using a number of techniques.
