Exoplanet Archive Frequently Asked Questions

Q:What happened to NStED and the stellar data it contained?

A: NStED (the NASA Stellar and Exoplanet Database) is no longer supported, but the exoplanet data is still available as part of the NASA Exoplanet Archive. The Exoplanet Archive also contains stellar parameters for exoplanet host stars and a limited number of data sets available for bulk download (see the Bulk Download page).

Searching by stellar parameters for non-planet-hosting stars is no longer available.

Q: When are planets included in the NASA Exoplanet Archive?

A: The list of planets is routinely updated once per week but may be updated more frequently depending on new significant exoplanet discoveries.

Q: How are the pre-generated plots created?

A: The pre-generated plots are produced by using the currently available data within the Exoplanet Archive. Thus, whenever there is an update to the archive information, the plots are re-created to ensure they are as current as possible. This purpose of these plots is to provide to the community fast access to presentation material that describe the current state of the exoplanets field in terms of their number and our understanding of their orbital and physical characteristics.
