What is OrbitalWiki?
OrbitalWiki is a searchable catalog of everything humanity has put in orbit, including satellites, stations, and debris, with a cited source on every field, plus a free read-only API for pulling the same data into your own tools.
The problem
Orbital data is scattered across raw element sets, launch logs, and operator sites that rarely agree with each other, and none of them tell you where a given number came from. OrbitalWiki reconciles the public sources into one record per object and keeps the provenance attached, so you can see exactly which source backs each field instead of taking it on faith.
What’s in it
Tens of thousands of tracked objects, searchable by name, operator, orbit regime, country, and status, each with orbital elements, launch history, and operator metadata reconciled from independent sources.
CelesTrak
Orbital elements: where each object is right now, updated continuously.
GCAT
Jonathan McDowell’s launch catalog: what launched, when, and on what.
Wikidata
Operator, mission, and manufacturer metadata for cross-referencing.
The full reconciliation process, how sources are matched, merged, and scored, is documented on the Methodology page.
The API
Every field visible in the catalog is available through a read-only developer API: the same reconciled data, with the same source attribution, so you can pull it into your own dashboards and tools instead of scraping.
Where things stand
OrbitalWiki is early-access software, still being built in the open. If the site is temporarily paused, that’s expected during this phase. Check Status for anything currently in progress, or reach us directly at hello@orbitalwiki.com.
