| Jul 10, 2023 at 15:17 | comment | added | Anton Sherwood | @Nosajimiki Then shouldn't spring and autumn also be in phase? | |
| Jul 10, 2023 at 14:35 | comment | added | Nosajimiki | @AntonSherwood It's been a while since I made this, but I think so. If the effect of eccentricity is greater than axial tilt, then both hemispheres will experience "Summer/Winter" at the same time. | |
| Jul 9, 2023 at 19:25 | comment | added | Anton Sherwood | Is it intentional that the diagram has summer matching summer and winter matching winter?? | |
| Jan 6, 2021 at 19:11 | comment | added | Nosajimiki | ... unless your point was just that I tilted the Earth in the wrong direction based on the eccentricity of its orbit. Since I was only meaning this to be an "Earth Like" world, it doesn't really matter as far as the answer goes, but still an informative catch. | |
| Jan 6, 2021 at 19:07 | comment | added | Nosajimiki | @Matrix That is only true on Earth between the latitudes of ~23°N and ~66°N . The Tropics and Polar regions do not have the same set of seasons as the temperate zones, and the southern temperate zone is inverted from the northern temperate zone; so, average weather actually is the main component. SEE: abc.net.au/news/science/2017-09-01/… . The point of the diagram is to show what would happen if the orbit were eccentric enough to cause global seasons as the OP requested, not a realistic depiction of the Earth's orbit as it is. | |

| Jan 5, 2021 at 5:45 | comment | added | c1moore | Sure, I get that, but if we're talking about an eccentric orbit that takes the planet to the edge of the Goldilocks zone, I imagine axial tilt would have a negligible effect. You seem to suggest the opposite, that even that far out, the axial tilt could cause one hemisphere to be significantly (uninhabitably) hotter than the other. Assuming a reasonable tilt (not ~90deg), I'm not sure I follow that train of thought. | |
| Jan 4, 2021 at 15:48 | comment | added | Nosajimiki | @c1moore Axial tilt plus eccentric orbits would cause compounding seasons; so, for one hemisphere to have a slightly cooler winter and warmer summer on a tilted world would mean dramatically colder winter and warmer summer on the other hemisphere. This would make 1 hemisphere completely uninhabitable for macro-organisms due to temperature variation and the other hemisphere would still be harsh due to violent storms... presuming your hot summers on the other side of the planet does not just boil off your Oceans into a runaway greenhouse effect. | |
| Jan 2, 2021 at 3:36 | comment | added | c1moore | Also, 'I will wait until the OP answers the "does the planet need to be habitable?" comment to respond to that question.' - It would be good to understand how much axial tilt vs distance from the sun due to eccentricity has on the temperature of the planet. It sounds like you're suggesting axial tilt would have a greater affect than distance. This may be true, but it seems wrong. Some equation/link/ect. would be helpful. | |
| Jan 2, 2021 at 3:33 | comment | added | c1moore | I would imagine removing axial tilt would have other effects on the planet that may affect the habitability of the planet. Currents amongst other processes that have made Earth such a perfect home are affected by the axial tilt. | |

| Dec 31, 2020 at 23:04 | comment | added | Nosajimiki | @Bryozoa The tilt of the axis means that the sun follows different paths through the sky at different times of the year. Tracking these paths using various forms of sundials were how many civilizations built their early calendars and how early farmers knew when to plant/harvest/etc. With no axial tilt, the sun would be in the same position in the sky during winter as in summer, just a bit dimmer because it is farther away. Measuring the brightness of the sun is much harder by primitive means than measuring its position. | |
| Dec 31, 2020 at 21:36 | comment | added | Mark | With sufficient eccentricity, distance variation will override almost any amount of axial tilt. | |
| Dec 31, 2020 at 20:47 | comment | added | Bryozoa | Thanks! I didn't quite catch the same track in the sky part. Why the same track on the sky will cancel the sun calendar (Since on the Earth equator regions definitely use the calendar)? | |
