Every object in orbit, on the record.
Search 16,022 tracked objects, inspect the source behind every field, and pull the same records through a read-only API. CelesTrak orbit data, GCAT launch records, and Wikidata enrichment, fused into one cited catalog.
Where the catalog is crowded.
Counts run against the live table, not a static graphic. Low Earth orbit dominates because active mega-constellations live there.
- LEO: 11,528 objects, 72.0% of catalog
- SSO: 3,382 objects, 21.1% of catalog
- GEO: 586 objects, 3.7% of catalog
- VLEO: 299 objects, 1.9% of catalog
- MEO: 184 objects, 1.1% of catalog
- HEO: 42 objects, 0.3% of catalog
A register, not scraped trivia.
A source on every field
Operator, launch mass, orbit class, and status are stored as source claims with confidence levels. Unknown data stays unknown.
Three catalogs, reconciled
CelesTrak orbital elements, GCAT launch records, and Wikidata metadata join on COSPAR and NORAD identifiers.
Open data, open API
The compiled database is ODbL licensed. Developers can inspect records in the UI or query them through the same API.
# fetch one object with source-backed fields $ curl -H "Authorization: Bearer ow_..." \ https://www.orbitalwiki.com/api/v1/satellites/25544 { "name": "ISS (ZARYA)", "orbit_class": "LEO", "claims": [{ "source": "WIKIDATA", "confidence": "CONFIRMED" }] }
Useful queries, ready to run.
Largest constellations, ranked
Starlink, OneWeb, and other constellations ordered by active member count.
Operators by active count
Satellite operators ranked by the number of active objects tied to them.
EU Earth observation
Active ESA and EU-funded Earth-observation satellites with orbit and operator detail.
Launched, never operational
Objects that reached orbit but were never recorded as operational.
