Overall: Rjjⁱⁱⁱ (talk) 20:55, 29 March 2026 (UTC) @Nrco0e: This is in pretty good shape! For full disclosure, I used a script that feeds snippets of the article and the cited sources to an LLM to help with spot-checking for verifiability and plagiarism. You can see the results at User talk:Rjjiii § LLM disclosure. I also checked everything manually. No issues with the article. The ALT0 hook sounds good. For the ALT1 hook to be promoted, it needs to be phrased as definite fact (maybe about what the scientists said?). I like the image a lot for the infobox. For DYK, it most likely won't be used as it's too hard to parse at thumbnail size. The DYK guideline at WP:DYKIMG says that " images in particular must display well in the small size of the {{main page image/DYK}} template (140x140 pixels, adjusted for aspect ratio)". The guideline does allow though for doing a modified version of this image even if that exact file isn't used in the article, so you could do (for example) a crop with fewer words or no words.

@Rjjiii: Thank you for the thorough review! I've made a textless version of the image here: File:TOI-1853 b size comparison textless.png. Let me know if that is acceptable. I was considering rephrasing ALT1 to say "scientists think that the Neptune-sized exoplanet TOI-1853 b (pictured) is entirely made of solid rock and water", but I still personally prefer ALT0. Nrco0e (talk • contribs) 21:30, 29 March 2026 (UTC)
- @Nrco0e: gotcha. I'll approve both hooks with a preference as well for ALT0. I don't have any issues with the image. If you (or the promoter) would like, the thumbnail can use the |link= parameter to still link to the original full image at File:TOI-1853 b size comparison.png with the legend. Good luck with the GA nomination, and I look forward to seeing this show up on the Main Page. Rjjⁱⁱⁱ (talk) 21:54, 29 March 2026 (UTC)

Orbit diagram

File:TOI-1853_b_orbit_diagram.png is confusing, because it is very different from the geometry as seen from Earth, and as described in the §Orbit and Temperature section directly next to it (viewed nearly edge-on, rather than from the top):

The orbit of TOI-1853 b is inclined 84.7° with respect to the sky plane, which allows it to transit its host star from Earth's point of view. Viewed from Earth, TOI-1853 b takes about 1.19 hours to transit its host star. Although the planet's orbital inclination with respect to its host star's rotation axis is unknown, it is predicted that the planet's orbital inclination is aligned with its star's rotation due to tidal interactions.

I suggest to either clarify in the image description that this isn't what its orbit looks like from Earth, but that it is a generic top-down view (assuming that the orbit is aligned, as predicted?); or to replace the image entirely. An image with the "correct" geometry could help illustrate the transit lightcurve and radial velocity plot in the §Discovery section. Renerpho (talk) 02:44, 31 March 2026 (UTC)

@Renerpho: Yeah, it would make more sense to have a diagram that takes inclination into account. I'll add this in a bit, thanks for doing the work for me! Nrco0e (talk • contribs) 03:34, 31 March 2026 (UTC)
