Talk:Mercury (planet)

Confusing: Sun in sky?
Article has “at perihelion, when the solar tide is strongest, the Sun is nearly still in Mercury's sky.”

What does that mean? The sun is always in Mercury’s sky, at some point on the planet. Sounds like some words are missing from that sentence. Can someone fix it? 2603:8001:5940:CF00:94AD:A25C:BBA0:B669 (talk) 19:55, 11 May 2023 (UTC)


 * Oh, I see they are using the word still to mean “not moving”. 2603:8001:5940:CF00:94AD:A25C:BBA0:B669 (talk) 19:55, 11 May 2023 (UTC)
 * I changed it to 'stationary' so as to avoid the ambiguity. Praemonitus (talk) 14:32, 5 October 2023 (UTC)

Incomplete edit summary
With regards this edit I just made, it should be "As with Venus, Earth and Mars, the source of the blackbody temperature no longer works, as seen on Talk:Venus so I've added an archive URL". Iggy (Swan) (Contribs) 16:03, 20 September 2023 (UTC)

Extreme places
I'm unclear what this is trying to communicate:
 * at the most extreme places: 0°N, 0°W, or 180°W

I understand the first is a reference to the north pole, but what are the longitudes? I would think that the extremes are the poles, subsolar point, and the night side. Praemonitus (talk) 22:45, 23 September 2023 (UTC)
 * Okay, I see now: it's redundant with the subsequent text in the same paragraph. Hence I removed it. Praemonitus (talk) 04:34, 25 September 2023 (UTC)

Fe-Si core
Currently the article claims the following:
 * Mercury appears to have a solid silicate crust and mantle overlying a solid, iron sulfide outer core layer, a deeper liquid core layer, and a solid inner core.

However, the current models indicate the core may instead be Fe-Si. For example: These look at a core with a Fe-S-Si composition: In that case perhaps it would make sense to say "the iron core is alloyed with uncertain abundances of silicon, sulfur, and carbon"?

 * I found a suitable source and updated the article accordingly. Praemonitus (talk) 14:52, 2 October 2023 (UTC)

Confusing: Planet or Element?
Some users look for the element, and find this page, thinking there would be a "Not to be confused with Mercury (Element)" or "the element" or "the element of the same name" Pinky the rancher slime (talk) 22:31, 5 October 2023 (UTC)
 * See WP:NOHATNOTE. The title of this page is not ambiguous. Readers searching for 'Mercury' are sent to the disambiguation page. Praemonitus (talk) 22:35, 5 October 2023 (UTC)
 * Oh, I didn't notice. I guess my ADHD didnt see it. Haha Pinky the rancher slime (talk) 00:20, 7 October 2023 (UTC)
 * Whoops I searched it on the web, now I get it. Pinky the rancher slime (talk) 00:23, 7 October 2023 (UTC)
