Wikipedia indexed “Clyde Tombaugh UFO sighting overview” in connection with the public record around Clyde Tombaugh UFO sighting, a 1949 UFO/UAP dossier centered on Las Cruces, New Mexico, United States. The source is useful because it fixes a checkable part of the record: who published the material, what topic it addressed, and how it connects to the timeline, witness layer, official response or later research around the case.
The accessible source text states: Clyde William Tombaugh was an American astronomer and telescope maker, best known for discovering Pluto in 1930, marking the first detection of what would eventually be recognized as the Kuiper belt. At the time, Pluto was referred to as the ninth planet in the Solar System, a classification that stood for over seven decades. In the archive context, that material is treated as a primary or secondary record to be compared with the case chronology rather than as a standalone proof of an extraordinary origin.
For Clyde Tombaugh UFO sighting, the relevant evidence categories include astronomer witness, named observer, later biographical reporting. The source should therefore be read alongside the dossier's witness accounts, timeline, evidence analysis and skeptical notes, especially where the material concerns official statements, video records, archival summaries or media reports.
The evidence boundary remains important. A source page can document that a report, document, video or database entry exists, but it does not by itself establish that the object or event was anomalous. This local record preserves the source's role in the case while keeping unresolved claims separate from confirmed facts. Original source URL: https://en.wikipedia.org/wiki/Clyde_Tombaugh#UFO_sightings
