The increased proximity to the Sun during perihelion does have some effects on the Earth's climate. However, these effects are relatively minor compared to the dominant factors that shape our climate, such as the tilt of the Earth's axis and the distribution of land and sea.
The word "perihelion" stems from the Greek words peri (near) and helios (sun). Because Earth moves in an elliptical—rather than perfectly circular—orbit, the distance between our planet and the Sun varies by about 3 million miles throughout the year. during which month is the earth closest to the sun link
