The difference between the two distances is about 5 million kilometers (roughly 3.1 million miles), meaning the Earth at aphelion is about 3.4% farther from the Sun than at perihelion.
The reason for this seasonal surprise lies in the shape of Earth's orbit. Our planet's path around the Sun is not a perfect circle, but an ellipse—a slightly elongated oval. In this elliptical orbit, the Sun is not at the exact center but at one of the two foci of the ellipse. As a result, the distance between Earth and the Sun changes throughout the year.
The exact date of perihelion is not perfectly fixed on the calendar. While it consistently falls in January, the precise day fluctuates between January 2 and January 5 from year to year. during which month is the earth closest to the sun link
"It is the great paradox of our planet," he began. "Most people assume that summer is hot because we are closer to the sun, and winter is cold because we are farther away. But if that were true, the entire planet would have summer at the same time. Australia wouldn't be having summer right now while we freeze."
Every year, our planet experiences two extreme points in its distance from the Sun: The difference between the two distances is about
Yes, you read that correctly. In July, when the Northern Hemisphere is enjoying beach weather and cookouts, the Earth is actually at its maximum distance from the sun.
Maya pulled back, intrigued. "Okay, you have my attention. Explain the physics, because my toes are telling me we should be roasting." In this elliptical orbit, the Sun is not
For residents of the Northern Hemisphere, discovering that the planet is physically nearest to the Sun in the dead of winter can feel completely backward. This phenomenon highlights a fundamental lesson in astronomy: distance from the Sun is not what determines our seasonal weather.

The difference between our closest approach () and our furthest retreat ( aphelion ) amounts to roughly 3 million miles (5 million kilometers). While that looks like a massive gap on paper, it accounts for a mere 3.3% variance in total distance, meaning our orbit remains highly circular compared to the wildly eccentric orbits of comets or other celestial bodies.
