Discussion Overview

The discussion revolves around Aphelion Day, specifically its occurrence in 2019 and its relationship to other astronomical events such as the Summer Solstice. Participants share thoughts on the significance of the day and its absence from calendars, as well as the implications of Earth's orbital eccentricity.

Discussion Character

  • Exploratory
  • Conceptual clarification

Main Points Raised

  • Some participants express celebration of Aphelion Day and share links to articles about it.
  • One participant notes that the preview of an article incorrectly states the year as 2018, but the content refers to 2019.
  • A participant comments on the relationship between Earth's axial tilt and its distance from the Sun, suggesting that tilt has a greater impact on seasons than distance does.
  • Another participant questions why Aphelion Day is not included on calendars, proposing that it should logically coincide with the Summer Solstice, but acknowledges that this is not the case due to variations in Earth's orbital eccentricity.
  • Historical context is provided regarding the drift of Perihelion and Aphelion dates over time, with a reference to a future event where Perihelion and the March Equinox may coincide.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the significance of Aphelion Day or its relationship to other astronomical events, indicating multiple competing views and unresolved questions.

Contextual Notes

The discussion includes references to historical variations in the timing of Perihelion and Aphelion, highlighting the complexity of Earth's orbital mechanics and the lack of fixed dates for these events.

How come Aphelion Day is not on the calendar? :mad:

One would, or could, logically think that Summer Solstice and Aphelion Day should coincide, but nay, it is a coincidence if that does happen due to the changes in the Earth's eccentricity of its orbit.

"The dates when Earth reaches the extreme points on its orbit are not fixed because of the variations in its eccentricity. In 1246, the December Solstice was on the same day as the Earth reached its Perihelion. Since then, the Perihelion and Aphelion dates have drifted by a day every 58 years. In the short-term, the dates can vary up to 2 days from one year to another."

Mathematicians and astronomers estimate that in the year 6430, over 4000 years from now, the timing of the Perihelion and the March Equinox will coincide"
