Elsewhere on Wiki, the initial character of the name is called an [[ʻokina|ʻokina]] ; it's not a diacritic, but an unicameral (no "capital" form) letter. Using the UNICODE character \x02BB (in HTML, "& #x02bb ;" without the spaces ; decimal 699) is recommended in preference to apostrophes, back-ticks or other approximations. Since Wiki can handle this, it's what should be used. |

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. — '''''<small>[[User:Insertcleverphrasehere|Insertcleverphrasehere]]<sup>([[User talk:Insertcleverphrasehere|or here]])<small><sub>([[Special:contributions/Insertcleverphrasehere|or here)]]<sup>([[WP:NPP|or here]])</sup></sub></small></sup></small>''''' 19:39, 21 June 2023 (UTC) |

Most of the rest of Hawaiʈian script is Latin/ Roman characters. And yes, that is an ʻokina in both "ʻokina" and "Hawaiʻi". (I only just found this out myself.) |

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. <!-- Template:Unsigned --><small class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Lamontcg|Lamontcg]] ([[User talk:Lamontcg#top|talk]] • [[Special:Contributions/Lamontcg|contribs]]) 17:19, 2 September 2023 (UTC)</small> <!--Autosigned by SineBot--> |

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.

Speaking as a non-astronomer: to me, "part of the sky" means the apparent constellation it's found in. But the rest of that para is about Vega's distance from the Sun at the time. Am I misunderstanding it, or is it a phrasing problem? [[User:Marnanel|Marnanel]] ([[User talk:Marnanel|talk]]) 14:56, 19 January 2024 (UTC) |
