How to Contribute Data to the NASA Exoplanet Archive

The NASA Exoplanet Archive includes peer-reviewed data on exoplanets and their host stars. Our priority is to keep up with the literature for new planets and to include newly derived values and other data when possible, based on our selection critera described in the first question of our FAQ.

For All Submissions

All data or values must come from a peer-reviewed and accepted publication. All contributions must include the reference information, including journal name, page and volume or astro-ph number.

Exoplanet and Stellar Parameters

If you have data you would like to have added to the archive and want to help us expedite the process, please use our Published Data Upload tool.

Contributing Datasets

If you have a mission or project dataset that you would like to contribute to the archive, we can host it. Please submit a ticket through the Helpdesk and a staff member will contact you.

Please note that the Exoplanet Archive only accepts reduced data and parameters, not raw or intermediate data products. We accept data on all confirmed planets in our archive, their host stars, and for stars in the Mission Stars and Mission Stars & ExoCAT lists. If you have data from a survey containing a mixture of hosts and non-host stars, please contact us to discuss your data.

A collection of contributed datasets currently available through the archive are linked to the Contributed Data page.
