When Is Earth Closest To The Sun

The exact time shifts due to:

Over very long timescales (tens of thousands of years), the date of perihelion precesses due to the slow rotation of Earth’s elliptical orbit (apsidal precession). Right now, perihelion aligns with northern winter, but in ~10,000 years, it will align with northern summer, dramatically changing seasonality.

For our friends in Australia, South Africa, and South America, early January is the middle of summer. This aligns perfectly with their intuition. When the Southern Hemisphere is tilted toward the sun (December to February), they receive direct sunlight and experience summer. The fact that Earth is also at perihelion (closest to the sun) during their summer amplifies their summers slightly.

Meanwhile, during their winter (July), Earth is at aphelion (farthest from the sun), making their winters slightly cooler than they would otherwise be.

Earth spins on an axis that is tilted 23.5 degrees relative to its orbital plane around the sun. This tilt is the sole driver of our seasons.

Think of it this way: Place your hands a few inches from a campfire. If you tilt your palms away, they feel cool. If you tilt them directly toward the fire, they feel hot. The distance change (3 inches) matters less than the angle of your hands.

Earth is closest to the Sun in early January, typically on January 3–5, about two weeks after the December solstice.

For 2026, perihelion occurs on January 4 at roughly 13:00 UTC.

At that moment, Earth is about 147.1 million km (91.4 million miles) from the Sun, compared to the average distance of ~149.6 million km (~93 million miles).

The next time someone shivers through a January day and jokes, “Well, at least we’re closer to the sun,” you can smile and set them straight.

Earth’s closest approach to the sun happens in early January—right in the middle of winter for the Northern Hemisphere. 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.

So mark your calendar for next January. Bundle up, look up, and think about this: you are riding a planet at its annual closest approach to a star—even if your frozen fingertips don’t believe it.

Earth reaches its closest point to the Sun—called perihelion—every year in early January, roughly two weeks after the December (northern‑hemisphere) solstice. The opposite point, aphelion (farthest from the Sun), occurs in early July.

When Is Earth Closest to the Sun? Understanding Perihelion When we think about the seasons, it’s natural to assume that summer happens because we are physically closer to the Sun. However, the reality of celestial mechanics is much more counterintuitive. In fact, for those living in the Northern Hemisphere, Earth is actually at its closest point to the Sun during the coldest part of the year.

This specific orbital milestone is known as perihelion. Here is everything you need to know about when it happens, why it occurs, and how it affects our planet. The Short Answer: Early January

Earth reaches its closest point to the Sun, or perihelion, around January 2nd to January 5th each year.

At this moment, Earth is approximately 91.4 million miles (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?

If Earth moved in a perfect circle, our distance from the Sun would never change. However, as Johannes Kepler discovered in the 17th century, planetary orbits are elliptical (oval-shaped).

While Earth’s orbit is nearly circular, it is slightly "eccentric." This slight stretch in our orbital path means there is about a 3-million-mile difference between our closest and farthest points. If We Are Closer in January, Why Is It Cold?

This is the most common point of confusion. If we are 3 million miles closer to our heat source in January, why are we shivering in Chicago or London? The answer lies in the tilt of Earth’s axis.

The Tilt: Earth doesn’t sit upright; it tilts at an angle of about 23.5 degrees.

The Seasons: Seasons are caused by which hemisphere is leaning toward the Sun, not how far away the planet is.

January Paradox: In January, the Northern Hemisphere is tilted away from the Sun. Even though we are physically closer to the Sun at perihelion, the tilt causes the sunlight to hit the Northern Hemisphere at a shallow angle, spreading the energy thin and creating winter.

Meanwhile, the Southern Hemisphere is tilted toward the Sun in January, which is why they experience their peak summer during perihelion. Does Perihelion Affect the Weather at All?

While the 3% difference in distance isn't enough to cause the seasons, it does have a subtle impact. Because Earth is closer to the Sun during the Southern Hemisphere's summer, their summers can technically be slightly warmer than those in the Northern Hemisphere. The exact time shifts due to:

Additionally, according to Kepler’s Second Law, planets move faster 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)

The next time you’re walking through a January snowstorm, remember: you’re actually as close to the Sun as you’ll be all year. It’s just the Earth’s tilt that’s keeping you cold.

Earth is closest to the sun during an astronomical event called perihelion , which occurs every year in early January At this point, Earth is approximately 91.4 million miles

(147.1 million km) away from the sun, which is about 3 million miles closer than its farthest point (aphelion) in July. www.thesuntoday.org Timing of Perihelion

The exact date and time change slightly every year because our calendar doesn't perfectly match Earth's elliptical orbit.

It is a common misconception that distance from the sun causes the seasons. In reality, seasons are driven by Earth's 23.5-degree axial tilt Explore Scientific Northern Hemisphere: In January, the Northern Hemisphere is tilted

from the sun, leading to winter despite being physically closer to the heat source. Southern Hemisphere: Conversely, the Southern Hemisphere is tilted

the sun during perihelion, which makes their summers slightly more intense than those in the north. Explore Scientific Key Effects of Perihelion

Every year, in the quiet heart of early January—usually around January 3rd or 4th —Earth reaches a milestone called perihelion

. This is the exact moment our planet is closest to the Sun, sitting about 91.4 million miles (147 million km) away.

The story of how we get there is one of subtle celestial geometry rather than dramatic seasonal shifts. The Great Ellipse

We often imagine Earth’s orbit as a perfect circle, but it is actually a slightly squashed oval, or an Over very long timescales (tens of thousands of

. This shape is carved by the gravity of our neighbors—especially the Moon and Jupiter—which tug on Earth just enough to keep its path from being perfectly round. Because of this oval path, there is always one point where we "swing in" close and another, six months later in July (called aphelion), where we "drift out" to our furthest distance. The Winter Paradox

For those in the Northern Hemisphere, perihelion feels like a trick of nature. How can we be closest to our star when the air is biting cold and the days are short? Tilt, Not Distance

: The 23.5-degree tilt of Earth's axis is the real director of our seasons. In January, the Northern Hemisphere is tilted

from the Sun, meaning sunlight hits us at a shallow, weak angle, even though we are physically closer to the source. The Southern Swing

What is perihelion? Here's why Earth is closer to the sun on January 3

Earth is closest to the Sun every year in early January, typically around January 2nd to 5th. This astronomical event is called perihelion, a term derived from the Greek words peri (near) and helios (Sun).

In 2026, Earth will reach perihelion on January 3 at 12:15 p.m. EST (17:15 UTC). At this precise moment, our planet will be approximately 91,403,637 miles (147,099,894 km) from the Sun's center. Understanding Perihelion and Aphelion

Because Earth's orbit is an ellipse (a slightly flattened circle) rather than a perfect circle, the distance between the Earth and the Sun varies throughout the year. Happy Perihelion 2026 — Earth's Closest Solar Encounter!
