When is Earth Closest to the Sun?
The Earth orbits the Sun in an elliptical path, which means that the distance between our planet and the Sun varies throughout the year. The point in the Earth's orbit when it is closest to the Sun is called perihelion, and the point when it is farthest from the Sun is called aphelion.
According to NASA, the Earth reaches perihelion around early January, specifically on:
At this time, the Earth is approximately 91.5 million miles (147 million kilometers) away from the Sun.
On the other hand, the Earth reaches aphelion around early July, specifically on:
At this time, the Earth is approximately 94.5 million miles (152 million kilometers) away from the Sun.
So, to summarize:
It's worth noting that the difference in distance between perihelion and aphelion has a relatively small effect on the Earth's climate, as the amount of solar energy the Earth receives is influenced by other factors, such as the tilt of its axis and the distribution of land and sea.
Report: Earth's Closest Approach to the Sun
Introduction
The Earth's orbit around the Sun is an elliptical path, which means that the distance between our planet and the Sun varies throughout the year. At certain times, the Earth is closer to the Sun, and at other times, it is farther away. This report aims to provide information on when the Earth is closest to the Sun, a phenomenon known as perihelion.
What is Perihelion?
Perihelion is the point in the Earth's orbit when it is closest to the Sun. At this point, the Earth is approximately 91.5 million miles (147 million kilometers) away from the Sun. This occurs when the Earth is on the opposite side of its orbit from the Sun, which happens around early January.
When is Earth Closest to the Sun?
The Earth is closest to the Sun around January 3rd or 4th every year. This date can vary slightly from year to year due to the elliptical shape of the Earth's orbit and the gravitational pull of other planets.
Perihelion Date and Distance for the Next Few Years:
| Year | Perihelion Date | Distance from Sun (miles) | Distance from Sun (kilometers) | | --- | --- | --- | --- | | 2023 | January 4th | 91,445,000 | 147,095,000 | | 2024 | January 3rd | 91,455,000 | 147,115,000 | | 2025 | January 3rd | 91,465,000 | 147,135,000 | when is earth closest to the sun
Why Does Perihelion Occur in January?
You might expect that perihelion would occur during the summer months in the Northern Hemisphere, when the Earth is tilted towards the Sun. However, the Earth's orbit is not synchronized with its axial tilt. The perihelion occurs when the Earth is at a specific point in its orbit, which happens to be around January 3rd or 4th.
Effects of Perihelion
Perihelion has some effects on our planet:
Conclusion
In conclusion, the Earth is closest to the Sun around January 3rd or 4th every year, a phenomenon known as perihelion. At this point, the Earth is approximately 91.5 million miles (147 million kilometers) away from the Sun. While perihelion has some effects on our planet, such as increased solar energy, it does not have a significant impact on Earth's temperature.

However, this calculation requires a good understanding of astronomy and orbital mechanics. For simplicity, the perihelion date and distance can be looked up or obtained from reliable astronomical sources.
Earth is closest to the Sun every year in early January. This specific point in our planet's annual orbit is known as perihelion. Key Details for 2026
In 2026, Earth reached perihelion on January 3 at 12:15 p.m. EST (17:15 UTC).
Distance: Approximately 91.4 million miles (147.1 million kilometers).
Comparison: This is roughly 3.1 million miles (5 million kilometers) closer than Earth’s farthest point, aphelion, which occurs in July. At this time, the Earth is approximately 91
Orbital Speed: Earth moves fastest at this point, traveling at about 30.3 kilometers per second. Common Misconceptions
Seasons: Many find it counterintuitive that Earth is closest to the Sun during the Northern Hemisphere's winter. Seasons are caused by the 23.5-degree tilt of Earth's axis, not its distance from the Sun.
Temperature: While the Sun's intensity is about 7% greater at perihelion than at aphelion, the effect on global climate is minimal because the Southern Hemisphere (which is tilted toward the Sun in January) is mostly water, which absorbs heat more steadily than land. Future Perihelion Dates
The exact date of perihelion shifts slightly each year due to the Gregorian calendar and gravitational influences from the Moon and other planets. According to Time and Date, upcoming dates include:

When is Earth Closest to the Sun? Understanding Perihelion and its Effects on Our Planet
The Earth's orbit around the Sun is not a perfect circle, but rather an ellipse. This means that the distance between our planet and the Sun varies throughout the year. At its closest point, the Earth is about 91.5 million miles (147 million kilometers) away from the Sun, and at its farthest point, it is approximately 94.5 million miles (152 million kilometers) away. But when exactly is the Earth closest to the Sun?
Perihelion: The Closest Point to the Sun
The moment when the Earth is closest to the Sun is called perihelion. Perihelion occurs when the Earth is at its closest point to the Sun in its elliptical orbit, which happens around early January each year. Specifically, perihelion typically falls on or around January 3rd or 4th. At this time, the Earth is approximately 91.5 million miles (147 million kilometers) away from the Sun.
Why Does Perihelion Occur in January?
It may seem counterintuitive that the Earth is closest to the Sun in January, when it's winter in the Northern Hemisphere. The reason for this discrepancy lies in the tilt of the Earth's axis, which is approximately 23.5 degrees. As the Earth orbits the Sun, its axis remains tilted in the same direction, resulting in the changing seasons.
The Earth's orbit is influenced by the gravitational pull of the other planets in our solar system, particularly Jupiter and Venus. These gravitational forces cause the Earth's orbit to vary slightly over time, a phenomenon known as orbital precession. As a result, the timing of perihelion shifts by about 1 day every 72 years.
Effects of Perihelion on the Earth's Climate
Perihelion has a significant impact on the Earth's climate. During this time, the Earth receives about 7% more solar energy than at its farthest point, aphelion. This increase in solar energy leads to several effects:

The Earth is closest to the Sun every year in early January . This specific point in our planet's elliptical orbit is called perihelion Time and Date The Timing of Perihelion
Perihelion typically occurs about two weeks after the December solstice. Because our calendar year doesn’t perfectly align with the Earth’s orbital path, the exact date and time vary slightly each year. Time and Date Perihelion Date Time (UTC) Distance and Visual Appearance At perihelion, the Earth is approximately 147 million kilometers
(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
in the sky at perihelion than at aphelion, though this difference is too subtle to detect with the naked eye. Why does Earth get colder when we are closest to the Sun 29 Dec 2025 —
The next time someone shivers on a cold January day and asks, “Why is it so cold if we’re closer to the Sun?” you’ll have the answer. Earth’s distance from the Sun changes throughout the year, but it’s our planet’s tilt—not its orbit—that dictates when you’ll need a coat or swimsuit.
So yes, Earth is closest to the Sun in January. It’s a wonderful reminder that in astronomy, common sense often needs a cosmic reality check.
| Event | Date | Distance from Sun | Hemisphere Effect | |-------|------|------------------|-------------------| | Perihelion | January 3–4 | ~91.4 million miles | Northern winter / Southern summer | | Aphelion | July 4–5 | ~94.5 million miles | Northern summer / Southern winter |
Many ancient cultures celebrated solar festivals in late December and early January—not just for the winter solstice (the shortest day), but also recognizing the sun’s “rebirth” and increasing strength. Without telescopes, they couldn’t measure the exact distance, but they observed that the sun’s apparent diameter in the sky is slightly larger in January.
It’s true! When Earth is at perihelion, the sun appears about 3.3% larger in diameter than it does in July. This is imperceptible to the naked eye (you shouldn’t look directly at the sun anyway), but precise instruments can measure it.
