It is difucult to distinguish a massive planet and a brown dwarf. However, it is estimated that the most massive exoplanets have a mass of around 13 Jupiter masses (but this is highly uncertain anyway). Despite this, the article has tens of objects with a mass higher than that. Many objects (such as GQ Lupi b/C) are often considered to be BDs but sometimes are considered to be planets as well but yet they are still here.Diamantinasaurus (talk) 17:26, 2 November 2023 (UTC)[reply]

Comment Sounds like a WP:POVFORK, but it also might have enough notability to last. I don't know enough about the policies surrounding space in the science community. However, the nom makes it just sound like a WP:IDONTLIKEIT. — Preceding unsigned comment added by Conyo14 (talk • contribs) 18:21, 2 November 2023 (UTC)[reply]

Leaning keep. This meets NLIST with a google news search. I think we could require every entry to have an reliable source declaring it as an exoplanet. AFAICT, I think the 13 Jupiter cutoff isn't widely agreed upon, so we probably shouldn't strictly require it, though maybe there's a place for distinguishing various cutoffs in the list. —siro χ o 00:14, 4 November 2023 (UTC)[reply]
Comment: I'm skeptical of the validity of this list. For example, HD 162020 b is now known to be a red dwarf. HIP 5158 c only has a minimum mass, but is listed as if the mass is well known. CT Cha b could be a brown dwarf or a planet; it's not clear. I think the list should only include objects that are conclusively known to be exoplanets with a well-bounded mass estimate.

This is effectively just a "list of objects between 10 and 30 Jupiter masses that orbit stars", and there isn't really a better way to make a "list of most massive exoplanets". Whether an object is considered a planet or a brown dwarf depends on either how it formed (while we can make some reasonable guesses, this isn't conclusively known) or a mass cutoff (the IAU uses 13 Jupiter masses, the NASA Exoplanet Archive uses 30). Maybe "objects described as planets in the scientific literature"? Leaning delete. SevenSpheres (talk) 16:17, 4 November 2023 (UTC)[reply]

Delete per inherent problems raised by Praemonitus. It is often not possible to get a precise estimate of a planet's mass. –LaundryPizza03 (d c̄) 22:26, 19 November 2023 (UTC)[reply]
