When Is Earth Closest To The Sun -

During perihelion, Earth is approximately (147 million kilometers) away from the Sun. By contrast, when Earth is farthest from the Sun in early July (a point called aphelion ), it sits about 94.5 million miles (152 million kilometers) away. Why Our Orbit Is Not a Perfect Circle

The Earth's orbit around the Sun is not a perfect circle, but rather an ellipse with the Sun at one of the two foci. This elliptical shape, described by Kepler's laws of planetary motion, results in the Earth's distance from the Sun varying throughout the year. The closest point in this orbit is called perihelion, while the farthest point is known as aphelion.

This is a difference of just over 3 million miles, or about 3%.

In July, when we are at aphelion (farthest away), the Northern Hemisphere is tilted toward the Sun, causing warmer temperatures.

In the 17th century, astronomer Johannes Kepler discovered that planets do not travel in perfect circles. Instead, they travel in , which are elongated or oval-shaped paths.

Seasons are about the angle of sunlight, not the distance. And that tilted axis of ours? It’s the real reason you need a parka in January and a swimsuit in July.

At this moment, Earth is approximately (147 million kilometers) away from the Sun. Contrast this with aphelion —the point where Earth is farthest from the Sun—which occurs in early July at a distance of about 94.5 million miles (152 million kilometers). Why Doesn’t the Distance Stay the Same?

(91.4 million miles) from the Sun. This is about 5 million kilometers closer than during (the farthest point), which occurs in early July. The Old Farmer’s Almanac Radiation Intensity: The Earth receives about 7% more solar energy in January than in July because of this closer proximity. Sun's Size: The Sun appears roughly 3.4% larger

While the change in distance does not cause the seasons, it does mildly influence their intensity.

During perihelion, Earth is approximately (147 million kilometers) away from the Sun. By contrast, when Earth reaches its farthest point from the Sun in early July—a point known as aphelion —it sits about 94.5 million miles (152 million kilometers) away. This means Earth is roughly 3 million miles closer to our star in January than it is in July. Why Earth's Distance Changes: Elliptical Orbits
