Earth axis definition
WebPrecession—the change in orientation of the Earth's rotational axis—alters the orientation of the Earth with respect to perihelion and aphelion. If a hemisphere is pointed towards the sun at perihelion, that hemisphere will be pointing away at aphelion, and the difference in seasons will be more extreme. WebMar 29, 2024 · The celestial equator and the ecliptic intersect at two points called the equinoxes (vernal and autumnal). During the course of the year, as Earth orbits the Sun, the latter is seen crossing the Equator twice, in March moving from the Southern Hemisphere into the Northern Hemisphere and in September moving in the opposite direction.
