How this service works
Asteroid or comet by name or designation: orbit class, NEO/hazardous flags, size, orbit elements, MOID and discovery.
Output
Returns a structured record for the requested small body including: full name, SPK ID, kind (asteroid or comet), orbit parameters (semi-major axis, eccentricity, inclination, perihelion, aphelion, period, MOID with Earth in AU and lunar distances, epoch), physical properties (diameter in km, estimated diameter range, albedo, spectral type, absolute magnitude H, rotation period), NEO and hazardous flags, discovery observation arc (first/last date, number of observations), condition code, a human-readable summary, verdict, reasons, and source attribution.
Example use cases
Research near-Earth asteroid threat level
“Can you pull up the full details on asteroid 99942 Apophis — is it classified as potentially hazardous, what's its estimated size, and how close does its orbit come to Earth?”
Identify comet orbital properties
“Give me the orbital elements for comet 1P/Halley — I need its period, eccentricity, inclination, perihelion and aphelion distances.”
Check asteroid physical characteristics
“What do we know about the physical properties of asteroid Ryugu — its diameter, albedo, spectral type, and absolute magnitude?”

Endpoint
GEThttps://space-objects.x402tookit.com/small-body?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need comprehensive small-body data for a specific known asteroid or comet by name, number, or designation. It combines orbital mechanics, physical properties, and hazard classification in a single call. Prefer this over close-approach or impact-risk endpoints when you need the full orbital profile rather than event-specific data. Best when the object is already identified by name or designation.
Side effects
- Object not found for given name/designation — returns empty or null result
- Ambiguous designation matching multiple objects — may return closest match or error
- Truncated data for poorly-observed objects — some fields will be null
- Network or payment authorization failure — HTTP 402 or 5xx
- Malformed query string — missing required 'name' parameter returns validation error
