"ecliptic south". In addition, the Earth is turning about an axis whose counterclockwise end points is a direction that we will once again leave nameless, but the part of this direction that is perpendicular to "ecliptic north" and "ecliptic south" we will call "summer solstice". The opposite direction we call "winter solstice". Ninety degrees counterclockwise from "summer solstice" as viewed from "ecliptic north" we call "fall equinox"; and the opposite direction we call "spring equinox". Thus the relationship between the celestial directions is as follows.
