New study on why Hydrogen Iceberg doesn't work

https://avi-loeb.medium.com/oumuamua-was-not-a-hydrogen-water-iceberg-1dd2f7a6107f Looks like the hydrogen theory is bust, so to my knowledge it looks like pretty much every proposed explanation for what this thing was has been shot down. — Insertcleverphrasehere^{(or here)_{(or here)^{(or here)}}} 19:39, 21 June 2023 (UTC)[reply]

Closest Approach to Earth and Golden Ratio

The closest approach distance in AU is currently listed as 0.1618 AU (24,200,000 km; 15,040,000 mi). The source of that is a web pages which list the closest approach as "24,000,000 km" or "15,000,000 mi" https://www.popularmechanics.com/space/news/a28958/first-interstellar-object-gets-a-name/ and those figures would result in 0.1604 AU or 0.1613 AU, not 0.1618 AU. The extra 200,000 km or 40,000 mi in those figures has been chosen by someone to make the closest approach match the Golden ratio to 4 significant figures. — Preceding unsigned comment added by Lamontcg (talk • contribs) 17:19, 2 September 2023 (UTC)[reply]

Ah, I see that the linked JPL database has the closest approach to Earth at the bottom listed as "0.16175 AU" which I've updated this page to have that value, since that is authoritative and the significant figures are supported by the uncertainty that the JPL data indicates.
