Overview: The NASA Exoplanet Archive provides data and tools to support community discovery and characterization of exoplanets and their host stars.

Data in the NASA Exoplanet Archive include stellar parameters, exoplanet parameters, and discovery/characterization data from the astronomical literature. The Archive also hosts mission and survey data, including Kepler pipeline data, such as candidate lists and data validation products, and ground-based surveys from SuperWASP and KELT. Tools provided for users to work with these data include a transit ephemeris predictor, light curve viewing utilities, a periodogram service and URL-based queries to the data table.
