Origin of oxygen molecules[edit]

Should be discussed somewhere I think ...

Layman's terms[edit]

Instead of NH₃, can't we just say ammonia so we're all on the same page? Kortoso (talk) 00:47, 23 January 2014 (UTC)[reply]

Cometary origin[edit]

It says "However, the ²H–¹H (i.e. D–H) ratio of Titan's atmosphere is (2.3±0.5)×10⁻⁴, nearly 1.5 times lower than that of comets. The difference suggests that cometary material is unlikely to be the major contributor to Titan's atmosphere.", which is currently unsourced. A bit above, it talks about the preferential loss of ¹⁴N vs. ¹⁵N due to low gravity and solar wind. Because H and D are much lighter, the same processes should be at work here, too, and to a greater degree. Hence, it seems to me that it is incorrect to a priori assume that because the D–H ratio of Titan's atmosphere does not match that of comets, its atmosphere cannot have come from comets. Or am I missing something? --JorisvS (talk) 16:52, 25 May 2015 (UTC)[reply]

Atmosphere density eg at surface[edit]

Article does not seem to say what the atmospheric density is at surface or at various heights.

Since pressure is 1.5 x earth and surface gravity is about 0.14 g, would surface density be about 10 x earth atmosphere ?
- In situ measurements of the physical characteristics of Titan’s environment fig 1 has a graph suggesting it is about 3 kg/m³.
Is this the article to cover suitability for aerobraking of spacecraft, parachute landings, and various forms of flight ? - Rod57 (talk) 18:00, 14 May 2017 (UTC)[reply]

Titan's surface air density is said to be 4.4 times Earth's. Since Earth has about 1.2 kg/m³ (~ 0.075 lb/ft³), Titan's air density must be about 5.3 kg/m³ (~ 0.3309 lb/ft³). One should verify it and add it into the article. --212.186.7.232 (talk) 10:57, 16 April 2019 (UTC)[reply]

Editing page for class[edit]

Hello, I am a graduate student in astronomy and astrobiology. I will be editing this page for a planetary atmospheres class. Tovarg (talk) 19:16, 12 June 2019 (UTC)[reply]

This is a moon exhibiting very complex chemistry and geological processes. I appreciate a Graduate student working on this fascinating article. I hope the Dragonfly mission to Titan is selected in July for development and launch. Cheers, Rowan Forest (talk) 23:03, 13 June 2019 (UTC)[reply]

@Tovarg: There are multiple inline citations that direct to your user page. This is not acceptable in Wikipedia. Please take time to address this at your earliest convenience. Inline citations mut be references to reliable sources. (Further info at: WP:RS.) Thank you. Rowan Forest (talk) 23:09, 13 June 2019 (UTC)[reply]

@Rowan Forest: Sorry about that. Is there a way I can see which inline citations need to be addressed? I read through the info you linked and all of my citations I included were automatically generated by Wikipedia.

Sure. In the introduction, there are 5 instances that the inline reference is stated as: User:Tovarg/sandbox#cite. Cheers, Rowan Forest (talk) 01:29, 14 June 2019 (UTC)[reply]
