Reddit User Says Claude Helped Flag a 116-Light-Year Planet Candidate in NASA TESS Data

A Reddit user says they used Claude Code with Opus 5.5 and Fable 5.1 to identify a possible previously unknown exoplanet in public NASA telescope data, but the object remains an unconfirmed planet candidate rather than a discovery. The claimed signal is a repeating dimming event from a star about 116 light-years away: roughly a 0.05% drop in brightness every 3.18 days, lasting about two hours, with the same pattern reportedly visible in TESS observations from 2025, 2020 and 2018.
