ExoQuery

Natural language interface for querying the NASA Exoplanet Archive.

Example: "What are the smallest exoplanets with an orbital period less than one day?"

Generated column search queries:

{
    "column_requests": [
        "planetary radius or mass (to determine size/smallest planets)",
        "orbital period of the planet"
    ]
}

Column results from embedding retrievals:

pl_radj,Planet Radius [Jupiter Radius],"Radius of the planet, measured in units of radius of Jupiter"
pl_rade,Planet Radius [Earth Radius],"Radius of the planet, measured in units of radius of the Earth"
pl_orbper,Orbital Period [days],Time the planet takes to make a complete orbit around the host star or system

Constructed NasaExoplanetArchive.query_criteria parameters:

{
  "select": "pl_name, pl_rade, pl_orbper",
  "where": "pl_orbper < 1 AND pl_rade IS NOT NULL",
  "order": "pl_rade ASC"
}
