WebFor any ellipse, the semi-major axis is defined as one-half the sum of the perihelion and the aphelion. In , the semi-major axis is the distance from the origin to either side of the ellipse along the x-axis, or just one-half the longest axis (called the major axis).

The main reason why we have seasons is due to the 23.5° axial tilt. The Earth is about 5,000,000km closer to the Sun at perihelion than it is at aphelion. This means that there is more energy from the Sun arriving at the Earth at perihelion.
