Earth doesn’t orbit the Sun in a perfect circle. Instead, we follow an elliptical (oval-shaped) path. Because of this slight stretch, there is one point in our orbit where we are at our nearest—this is called .

While you might be experiencing cold weather, you can know that in early January, the planet is experiencing its closest solar encounter, providing slightly more intense sunlight to the southern hemisphere, and slightly warmer perihelion sunlight to the northern hemisphere than if it were a perfect circle, despite the tilt-induced winter.

Perihelion occurs during their summer, which can lead to slightly more intense solar radiation compared to Northern Hemisphere summers. The Opposite: Aphelion during which month is the earth closest to the sun link

Intuition is a powerful thing. Humans naturally associate heat with closeness, so without astronomical education, we assume summer must be the closest month. In reality, the axial tilt is the dominant force for temperature.

On a much longer astronomical timescale, the date of perihelion shifts due to a phenomenon called orbital precession. Gravitational tugs from other planets, particularly giants like Jupiter and Saturn, cause the entire ellipse of Earth's orbit to slowly rotate. Roughly 13,000 years from now, this slow drift will cause perihelion to occur in July instead of January, reversing the current dynamic.

This phenomenon surprises many people living in the Northern Hemisphere, who are experiencing the depth of winter during this time. The Science of Perihelion Instead, we follow an elliptical (oval-shaped) path

While it doesn’t flip the seasons, being closer to the sun does have measurable effects:

At perihelion, Earth is roughly 91.4 million miles (147 million kilometers) from the Sun.

While the north experiences winter, the Southern Hemisphere is tilted toward the Sun. It receives more direct, concentrated sunlight and enjoys longer days, bringing warm summer temperatures. Perihelion occurs during their summer, which can lead

While the distance change does not cause the seasons, it does impact solar intensity. When Earth is at perihelion in January, the planet receives about than it does at aphelion in July. This slight boost in solar radiation makes Southern Hemisphere summers slightly warmer overall than Northern Hemisphere summers, though global weather patterns and ocean distribution largely equalize the global climate.

The answer to the question, "During which month is Earth closest to the Sun?" is . This astronomical event is known as perihelion . While it's a fascinating and measurable event that brings us about 5 million kilometers closer to our star, it is Earth's axial tilt , not its orbital distance, that dictates our familiar patterns of seasons. The January perihelion gives the Southern Hemisphere a slightly warmer summer and causes Earth to move at its fastest orbital speed, subtly influencing the rhythm of our year.

Although the seasons aren't caused by orbital distance, perihelion does have some notable effects:
