Talk:2792: Summer Solstice

Great minds think alike*. Hadn't read down here when I leapt in and added that link (and made some other very minor tweaks). Or at least leapt in once I'd found it myself (not rembering its title or enough of its keywords), having had to trawl through Category:Astronomy and visit almost all likely titles and several unlikely ones. Which was enjoyable, so not a problem. ;) 172.70.85.92 00:58, 22 June 2023 (UTC) * - fools never differ... :P

I think there's a 3rd option for what the "fix" entails: eliminating Earth's axial tilt so it's always equinox (12 hour days almost everywhere, perpetual dawn at the poles). The title text specifies "on the equator", not "near" the equator. The only way for eclipses always "on" the equator is if the equator is always aligned with the ecliptic. - Frankie (talk) 02:06, 22 June 2023 (UTC)

I think that to make the solstices match the earliest sunrise/sunset might require straightening out the Earth's tilt as well. Making it a circular orbit I think actually makes the summer solstice even further from the latest sunset (but the winter solstice closer to latest sunrise). [1]. Oh but straightening the tilt would mean no more solstices at all, hm. Maybe what's required is an elliptical orbit but with the sun at the center rather than a focus.
