The Earth is closest to the Sun every year during the month of This specific point in Earth's elliptical orbit is called perihelion
. It typically occurs in early January, about two weeks after the December solstice. Fast Facts about Perihelion 2026 Date: In 2026, Earth reached perihelion on at 17:16 UTC. At this point, the Earth is approximately 147.1 million kilometers (91.4 million miles) from the Sun. Earth travels at its maximum orbital speed—about 30.3 kilometers per second —when it is closest to the Sun. Sun's Appearance: Because we are closer, the Sun appears about 3.4% larger in the sky and is roughly 7% more intense
than at its farthest point in July, though this is not detectable to the naked eye. National Geographic

While it might feel like the dead of winter for those in the Northern Hemisphere, Earth is actually at its closest point to the sun during the month of January.
This astronomical event is known as perihelion. Here is a deep dive into why this happens, why it doesn’t make the weather hot, and how our orbit affects life on Earth. What is Perihelion?
The word "perihelion" comes from the Greek words peri (near) and helios (sun). It refers to the specific point in a planet's orbit where it is physically closest to the star it revolves around.
For Earth, perihelion typically occurs about two weeks after the Winter Solstice, falling between January 2nd and January 5th each year. At this moment, Earth is approximately 91.4 million miles (147 million kilometers) away from the sun. The Myth of Distance and Temperature
A common misconception is that seasons are caused by Earth’s distance from the sun. If that were true, the entire planet would experience summer in January.
In reality, the difference in distance between our closest point (perihelion) and our farthest point (aphelion, which occurs in July) is only about 3 million miles—a mere 3% difference. This change is too small to dictate our seasons. during which month is the earth closest to the sun link
Instead, seasons are caused by the 23.5-degree tilt of Earth’s axis. In January, even though we are physically closer to the sun, the Northern Hemisphere is tilted away from it, leading to shorter days and colder temperatures. Meanwhile, the Southern Hemisphere is tilted toward the sun, enjoying the height of summer. Why Does the Date Shift?
You might notice that perihelion doesn't land on the exact same day every year. This is due to the complexities of orbital mechanics:
The Moon’s Pull: The gravitational tug of the moon causes Earth to "wobble" slightly in its path.
Leap Years: Our calendar year isn't a perfect match for the time it takes to orbit the sun, causing the timing of astronomical events to drift slightly.
Other Planets: The gravitational pull from giants like Jupiter and Saturn can subtly alter Earth’s orbital path over long periods. How Perihelion Affects the Earth
While it doesn’t flip the seasons, being closer to the sun does have measurable effects:
Solar Intensity: The sun appears about 3% larger in the sky in January than in July. Furthermore, the Earth receives about 7% more solar energy (radiation) during perihelion.
Orbital Speed: According to Kepler’s Second Law of Planetary Motion, planets move faster when they are closer to the sun. This means Earth is traveling at its maximum orbital speed in January, which is why winter in the Northern Hemisphere is about five days shorter than summer.
Southern Hemisphere Summers: Because perihelion coincides with the Southern Hemisphere's summer, their summers can technically be slightly warmer than Northern Hemisphere summers, though ocean distribution usually tempers this effect. The Earth is closest to the Sun every
If you are looking for the "link" between the calendar and the cosmos, remember that January is the month of proximity. We are closest to our star during the coldest month for the north, proving that in astronomy, tilt matters much more than distance.
Earth is closest to the sun every year during the month of This astronomical event is known as perihelion
. While the exact date shifts slightly each year due to variations in Earth's orbit and the calendar, it typically occurs between January 2 and January 5 . For example, in 2026, perihelion occurs on January 3. Key Facts About Perihelion
The Earth is closest to the sun in . This point in Earth’s orbit is known as perihelion Cosmic Proximity Review: January's "Hidden" Heat
If you're in the Northern Hemisphere, January usually feels like the
time to visit the sun. But in a plot twist that defies common logic, our planet actually reaches its closest approach to our parent star during this freezing month.
The Seasons, the Equinox, and the Solstices - National Weather Service
Earth is closest to the Sun in early January each year (perihelion). Perihelion typically occurs around January 3–5; aphelion (farthest point) occurs in early July.
This is the million-dollar question. If we are 3 million miles closer to the sun in January, why is it freezing in New York, London, and Paris? In January (Perihelion): The Northern Hemisphere is tilted
The answer lies in a single, critical factor: The Tilt of the Earth's Axis (Seasons).
Distance from the sun is not what causes our seasons. The seasons are caused by the 23.5-degree tilt of the Earth on its axis.
Think of it like a flashlight. If you shine it straight down onto a piece of paper, the light is hot and bright. If you tilt the flashlight, the same amount of light spreads out over a bigger area and becomes dim and cool. The tilt trumps the distance.
A: Using Kepler’s Laws of Planetary Motion. Kepler proved that planetary orbits are ellipses (ovals), not perfect circles. Because the orbit is an ellipse, there must be a point of closest approach (perihelion) and a point of farthest distance (aphelion). Astronomers calculate this using radar measurements and Newtonian physics.
Because this is a long article, we can dig deeper into the "link" between months and proximity. You might be surprised to learn that this alignment hasn't always been the case—and it won't stay this way forever.
Due to a phenomenon called axial precession (a slow wobble of Earth’s axis, like a spinning top slowing down), the timing of perihelion shifts very gradually over a 26,000-year cycle.
So, the specific month in which the Earth is closest to the sun is not fixed for eternity. However, for your lifetime and the next several thousand years, the answer will remain January.
To provide the direct keyword link you are looking for: The Earth is closest to the sun during the month of January.
More specifically, the exact date varies slightly from year to year, but it usually falls between January 2nd and January 5th. For example, in recent years, perihelion has occurred around January 4th at roughly 1:00 AM UTC.
So, if you are searching for the "closest to the sun link," remember the link to January. It is a fixed astronomical event that happens shortly after the New Year.
