Short answer
The Black Knight label brands a modern orbital myth. Famous NASA stills show a 1998 STS-88 thermal cover, not a 13,000-year alien satellite.
Identification
Field-guide traits below describe the viral silhouette and the mainstream debris ID. Documentary STS-88 frames appear under Documentary photos. AI plates are illustrations of that irregular debris-like form - not proof of an ancient probe.
Size and shape
Soft, multi-lobed cover geometry that changes with tumble. Lore invents bus-sized ancient craft the photos do not support.
Exterior
Dark against Earth when the reflective MLI face is shadowed; sun glints on foil edges. Material of the documented object is multilayer insulation textile - not unknown alien alloy.
Lights and markings
No insignia; glints are lighting, not windows.
Motion and behavior
Brief free-flyer after EVA, then reentry. Millennia-long polar orbit is claim-only.
Lookalikes
Other EVA debris, rocket bodies, Cold War sat misIDs, and speculative CGI probes.
Overview
Class: alleged satellite / mystery-object myth (mystery-object). Region: global internet lore; photos from STS-88 LEO. Parent hub target: unexplained mysteries list.
Origin of the legend
Twentieth-century radio and satellite anecdotes were stewed together online, then glued to STS-88 stills after NASA page reshuffles made original captions harder to find - a confusion Oberg and later fact-checkers describe as skipped journalistic context, not a cover-up.
Evidence and mainstream view
Evidence level: E. Consensus: folklore plus misidentification. No authenticated ancient satellite; STS-88 object explained as lost thermal cover.
Timeline
See structured timeline (Tesla notes, delayed echoes, 1950s–60s press, 1998 STS-88 debris, modern viral loops).
Sightings and stories
Attributed accounts above separate flight-ops documentation (Ross/Cabana/Oberg) from Armagh’s myth diagnosis. Do not merge them into one continuous detection.

In popular culture
YouTube “ancient satellite” shorts, tabloid roundups, and conspiracy podcasts - often cropping NASA frames without EVA context.
