Astronomy: The earth moves around the sun, January is closest to the sun, and July. . .

The distance between the earth and the sun has little to do with the temperature on the earth, but depends on whether the sunlight is direct or not.

The straighter, the more solar radiation per unit area, the higher the temperature, the more inclined and the lower the temperature.

Look at the picture and you will understand that the same area and the same light density will directly receive more light.
