Description
English: While in reality the Earth goes in an orbit around the Sun, it seems from the Earth that the Sun moves over the ecliptic (red) on the celestial dome. When the Sun seems to pass through the vernal equinox (longitude 0°), the longitude of the Earth itself is 180° longitude.
Français : Alors qu’en réalité la Terre est en orbite autour du Soleil, il semble que le Soleil, vu depuis la Terre, se déplace le long de l’écliptique (en rouge) sur la voute céleste. Quand le Soleil semble passer sur l’équinoxe vernale (à la longitude 0°), la longitude de la Terre elle-même est de 180°.
Português: Enquanto na realidade a Terra orbita em torno do Sol, a aparência da Terra é de que o Sol se move na órbita elíptica (em vermelho) na cúpula celestial. Quando o Sol parece passar através do equinócio primaveril (longitude 0º), a longitude da Terra para si mesma é de 180º de longitude. _leoandreh
