During Which Month Is The Earth Closest To The Sun Link ((link)) → 〈QUICK〉
"Look at the size," Elias prompted. "Compare it to a photo taken in July. Right now, the Sun is about 3% larger in our sky than it is in the middle of summer."
I'll search for reliable information. have gathered some initial search results. I will now need to open several of these pages to extract more detailed information for the article. have gathered information from various sources. Now I need to write a long article. The article should cover: introduction answering the question (January), explanation of elliptical orbit and terms perihelion/aphelion, specific dates and distances, why it happens in January (axial tilt vs. distance), common misconceptions, historical context, and a link to a reliable source for further reading. I'll structure the article with headings, include a link to a source like NASA or a reputable astronomy site.'s a common belief that summer's warmth comes from being closer to the Sun. So it might surprise you that our planet is actually at its greatest distance from its parent star during the hottest months.
Across these two years, the distance varies by only about 3% throughout a single orbit.
The word "perihelion" stems from the Greek words peri (near) and helios (sun). Because Earth moves in an elliptical—rather than perfectly circular—orbit, the distance between our planet and the Sun varies by about 3 million miles throughout the year. during which month is the earth closest to the sun link
The 3% increase in solar intensity during perihelion does have a subtle effect, however. It makes winters in the Northern Hemisphere slightly milder than they would be if the orbit were perfectly circular, and it intensifies the summer heat in the Southern Hemisphere. The Changing Dates of Perihelion
When is Earth Closest to the Sun? Understanding Perihelion (2026 Update)
The timing of perihelion is not static over very long periods. Due to a slow, continuous change in the orientation of Earth's elliptical orbit—a phenomenon known as apsidal precession —the date of perihelion shifts gradually over a cycle of about 21,000 years. Approximately 10,000 years from now, the perihelion will occur in July, meaning the Northern Hemisphere's summers will be hotter and its winters colder, due to the combined effect of axial tilt and proximity to the Sun. "Look at the size," Elias prompted
The reason for this phenomenon lies in the shape of Earth's orbit. Earth's orbit is not a perfect circle; it is an —an elongated circle. Therefore, the distance between the Earth and the Sun varies slightly throughout the year. Perihelion: Greek for "near the sun" (January). Aphelion: Greek for "away from the sun" (July). Why Doesn't Closest Mean Hottest?
Our planet's orbital dance is not static. The timing of perihelion and aphelion slowly changes over millennia. Currently, perihelion occurs in January and aphelion in July. However, the dates drift by about due to gravitational interactions with other planets. In approximately 10,000 years , perihelion will occur during the Northern Hemisphere's summer, which would significantly alter the intensity of the seasons.
The exact date and time of perihelion shift slightly from year to year. This is due to the gravitational influence of other planets, particularly the Moon and Jupiter, as well as the fact that our calendar doesn't align perfectly with Earth's orbit. Here is a short-term look at the event: have gathered some initial search results
The Earth is closest to the Sun during the month of This annual astronomical milestone is known as perihelion
Because Earth reaches perihelion in January, it travels at its maximum orbital speed during this time—moving at roughly 19 miles (30.3 kilometers) per second. As a result, winter in the Northern Hemisphere (and summer in the Southern Hemisphere) is about five days shorter than the opposite season in July, as the Earth quickly swings around the Sun.
