It is a common misconception that seasons occur because of Earth's elliptical orbit around the Sun, with winter occurring when Earth is farthest away from the Sun, and summer when it is closest to it. However, our planet's distance from the Sun has little effect on the onset of seasons. read more
Yes, even the distance from the sun also effect temperature on earth. But the effect on temperature due to earth's tilt is more than the effect of distance of earth from sun. To be more precise Northern Hemisphere's summers are less hotter than southern hemisphere's summers. read more
However, our planet's distance from the Sun has little effect on the onset of seasons. In fact, Earth is closest to the Sun, or at its Perihelion, around the Northern Hemisphere's winter solstice, while it is farthest away from the Sun, or at its Aphelion, around the north's summer solstice. read more
Earth's orbit, although elliptical, is so close to round (only 1.7 percentage points from being perfectly round) that Earth's distance from the Sun does not vary enough to affect the seasons. Indeed, Earth is closest to the Sun each year on January 4, when it is winter and cold in the Northern Hemisphere. read more
