What causes perihelion and aphelion?
Explanation: Because the orbit of Earth around the Sun is not a perfect circle, it is almost a perfect circle but yet it is an ellipse with an eccentricity of 0.017. When the planet is closest to the Sun it is at Perihelion and when it is further away it is at Aphelion.
Does aphelion and perihelion affect seasons?
Distance Does Not Cause 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.

Is Earth going near the sun?
