[edit]I basically just translated the article from the Russian version, and I don’t know how to convert the Russian references. The starbox was rewritten as well. I found references for the star (and the three visual companions) but the planet remains unreferenced. Please help adding some references. Astronomical Editor (talk) 14:29, 13 September 2025 (UTC)
- This is the source the Russian page uses to claim a planet, but the text doesn't appear to mention this star. It does have an entry in the VizieR table with a "mass of secondary" listed, but that doesn't mean there's evidence of a companion; there's a similar entry for every Hipparcos star.

- There is no discovery, just an automated program running an equation that takes the difference between Hipparcos-Gaia DR2 proper motions of the star and derive astrometric properties for an orbiting object causing the proper motion anomaly. That is at best a candidate detection. 21 Andromedae (talk) 13:17, 15 September 2025 (UTC)
