Revision of solar terms

No. The change of the distance between the earth and the sun in a year has little influence on the earth's climate. For the northern hemisphere, the closest time to the sun is the winter solstice, but it is a colder season. It can be seen that the change of the distance between the sun and the earth is not the cause of seasonal changes.

The change of the four seasons of the earth is mainly caused by the fact that the equatorial plane of the earth does not coincide with the revolutionary plane (ecliptic plane) and there is an included angle (ecliptic angle). And it has no effect on the equator (so there are no four seasons in the equator). The existence of ecliptic angle makes the solar altitude angle in the temperate zone of the northern hemisphere larger in summer and smaller in winter, thus affecting the sunshine intensity. Causing the seasons to change.
