The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth’s axis points towards the sun, it is summer for that hemisphere. … Midway between these two times, in spring and autumn, the spin axis of the earth points 90 degrees away from the sun.
