occurs in early July (July 4–6 typically). Distance: ~152.1 million km (94.5 million miles). At aphelion, the Sun appears slightly smaller, and Earth moves slower (~29.3 km/s). when is earth closest to the sun

The term "perihelion" stems from the Greek words peri (meaning "near") and helios (meaning "sun"). It defines the point in an orbit where a planet is nearest to the star it circles. For Earth, this occurs because its orbit is not a perfect circle, but rather an ellipse—a slightly elongated oval shape. This elliptical path was first accurately described by Johannes Kepler in the 17th century, revolutionizing our understanding of the solar system. As Earth travels along this orbit, its distance from the Sun fluctuates. At perihelion, Earth is approximately 91.4 million miles (147.1 million kilometers) away from the Sun. Roughly six months later, in early July, Earth reaches aphelion , its farthest point, drifting out to about 94.5 million miles (152.1 million kilometers).

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. The term "perihelion" stems from the Greek words

Additionally, according to Kepler’s Second Law, planets move in their orbits when they are closer to the Sun. This means Earth is actually traveling at its top orbital speed in early January. As a result, winter in the Northern Hemisphere is about five days shorter than summer! Summary of Key Dates Perihelion (Closest): Early January (~91.4 million miles) Aphelion (Farthest): Early July (~94.5 million miles)
