TheNASA Exoplanet Archive is an online astronomicalexoplanet catalog and data service that collects and serves public data that support the search for and characterization of extra-solar planets (exoplanets) and their host stars. It is part of theInfrared Processing and Analysis Center and is on the campus of theCalifornia Institute of Technology (Caltech) inPasadena, CA. The archive is funded byNASA and was launched in early December 2011 by theNASA Exoplanet Science Institute as part of NASA's Exoplanet Exploration Program. In June 2019, the archive's collection of confirmed exoplanets surpassed 4,000.[1] (Compare: As of 26 March 2025, there are 5,867 confirmedexoplanets in 4,377planetary systems, with 985 systemshaving more than one planet.[2])
The archive's data include published light curves, images, spectra and parameters, and time-series data from surveys that aim to discover transiting exoplanets. The archive also develops Web-based tools and services to work with the data, particularly the display and analysis of transit data sets from theKepler mission andCOnvection ROtation and planetary Transits (CoRoT) mission, for which the Exoplanet Archive is the U.S. data portal. Other astronomical surveys and telescopes that have contributed data sets to the archive includeSuperWASP,HATNet Project,XO,Trans-Atlantic Exoplanet Survey andKELT.
According to third-partyweb analytics providerSimilarWeb, the company's website has over 130,000 visits per month, as of January 2015.[3]
The Exoplanet Archive contains objects discovered through allmethods (radial velocity,transits,microlensing,imaging,astrometry,eclipse timing variations, andtransit timing variations/TTV) that have publicly available planetary parameters, with a mass (or minimum mass) equal to or less than 30 Jupiter masses.[4]
In addition to providing access to large public data sets, the Exoplanet Archive has developed several tools to work with exoplanet and stellar host data.[6]
The Exoplanet Archive serves photometric time-series data from surveys that aim to discover transiting exoplanets, such as the Kepler Mission and CoRoT. The database provides access to over 22 million light curves from space and ground-based exoplanet transit survey programs, including:
The Exoplanet Archive offers search and filtering capabilities for exoplanet stellar and planetary properties, Kepler planetary candidates, and time series data sets. All data in the Exoplanet Archive are vetted by a team of astronomers and the original literature references are available.
The Exoplanet Archive supports interactive visualization of images, spectra, and time series data and maintains its own stellar cross-identification to minimize ambiguity in multiple star components.
