Welcome to JPL’s SSD (Solar System Dynamics) and CNEOS (Center for Near-Earth Object Studies) API (Application Program Interface) service. This service provides an interface to machine-readable data (JSON-format) related to SSD and CNEOS.
The following APIs are available. A solid understanding of JSON is necessary to make use of these APIs.
|CAD||Asteroid and comet close approaches to the planets in the past and future|
|Fireball||Fireball atmospheric impact data reported by US Government sensors|
|NHATS||Human-accessible NEOs data|
|Sentry||NEO Earth impact risk assessment data|
versionfield in the API output to detect any change (in which case, you should come back to this site to see what, if anything, in the data format/output changed).
Every attempt has been made to ensure our APIs follow the REST architecture style. Although URI path mapping is often associated with REST APIs, they are not a requirement of REST. Because these APIs only get data from a database (no updates or deletes), query parameters are specified instead of using URI path mapping. Similarly, only GET and POST HTTP-request types are supported.
