How this service works
Asteroid and Comet Lookup (NASA/JPL). Asteroid and comet lookup (NASA/JPL Small-Body Database) by name, number or designation (Apophis, 433 Eros, 2024 YR4, 1P/Halley): near-Earth and potentially-hazardous flags, size, albedo, rotation, orbit, Earth MOID, the next close approaches to Earth in km and lunar distances, and discovery details. Public domain.
Output
A JSON object indicating whether the small body was found, its kind (asteroid or comet), name, physical properties (size, albedo, rotation), orbital parameters, Earth MOID, near-Earth and potentially-hazardous boolean flags, a list of upcoming close approaches to Earth with distances in km and lunar distances, and discovery details.
Example use cases
Hazard check for newly discovered asteroid
“I just heard about asteroid 2024 YR4 — can you tell me if it's flagged as potentially hazardous and how close it will get to Earth on its next approach?”
Historical comet research
“Look up 1P/Halley for me — I need its orbital period, physical size, and any upcoming close approaches to Earth.”
Educational fact sheet on a named asteroid
“Give me all the details on 433 Eros — its size, albedo, rotation rate, Earth MOID, and discovery info.”

Endpoint
GEThttps://saylorinnovations.com/api/asteroids/lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative NASA/JPL data on a specific asteroid or comet by name, number, or IAU designation. It is ideal for hazard assessment, orbital lookup, close approach scheduling, and educational summaries of known small bodies. Prefer it over general web searches when structured, machine-readable orbital and physical data is needed.
Side effects
- Body not found: returns found=false when the name, number, or designation doesn't match any NASA/JPL record
- Ambiguous designation: multiple matches may require a more specific query
- Invalid query format: malformed or empty name parameter returns an error
- Network timeout: upstream NASA/JPL database unavailability causes request failure
