GRIDINT RESEARCH · DATA HUB

Exoplanets.

Every confirmed planet beyond this solar system with a measured radius — 4,706 worlds from NASA's Exoplanet Archive, each with its orbital period, radius, discovery method, and year. The archive is the census of a working field; this catalog holds it as published, updated by dated edition. Where a method cannot see, the gap is in the picture — absence drawn, never filled.

How this hub was made.

What this set is. Every confirmed planet with BOTH a measured radius and a measured orbital period, from NASA's Exoplanet Archive. It is a separate pull from the report's, five rows apart; the two converge to one fetch at the next edition, and until then each states its own vintage. 4,706 records. Pulled 2026-08-26T10:35Z.

The methodology note for this hub — source classes, what the source does and does not establish, quantified uncertainty — is being written.

Every edition, dated.

  • Edition 1 published 2026-08-26 · data cutoff 2026-08-26 · first edition

A hub changes only as a new dated edition, on the institute's word — never on a schedule. Collection continues underneath; publication is deliberate.

Verify this hub.

Verification extracts — the working records with their receipts, attribution first, pointing at the origin. We never provide data; the source is the authority, this hub is the lens.
