Happy Aphelion Day marks the point when Earth is farthest from the Sun, which varies each year due to changes in the Earth's orbital eccentricity. The article linked clarifies a typo regarding the year, confirming the event occurs in 2019. The discussion highlights that Aphelion Day is not officially recognized on calendars, despite its significance. It notes that the dates for Aphelion and Perihelion (closest point to the Sun) are not fixed and can shift by up to two days annually, influenced by the Earth's orbital variations. Historically, these dates have drifted, with significant alignments occurring every 58 years. In the distant future, projections suggest that the timing of Perihelion may coincide with the March Equinox in the year 6430.
