In , 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
You cannot “see” Earth being closer to the sun, but you can observe two subtle effects:
The Earth is closest to the Sun during perihelion, which typically occurs around January 3rd or 4th. This event has significant effects on our planet's climate, including variations in global temperatures, weather patterns, and ocean currents. Understanding perihelion and its implications can help us better appreciate the complex interactions between the Earth and the Sun, and how they impact our planet's dynamic systems.
The net result:
The answer is , not distance.
Earth's seasons are caused by its , not its proximity to the Sun. In January, the Northern Hemisphere is tilted away from the Sun, receiving less direct sunlight and experiencing shorter days, which outweighs the modest increase in solar intensity from being closer to the star. Notable Effects of Perihelion
Conversely, the Southern Hemisphere is tilted toward the Sun in January, which is why it experiences summer during perihelion. The difference in distance— when is earth closest to the sun
The point in an object's orbit where it is nearest to the Sun. The word comes from the Greek words peri (around) and helios (sun).
Because the sun's gravitational pull is strongest at perihelion, Earth accelerates to its maximum orbital speed of roughly
In conclusion, Earth’s closest approach to the Sun is a reminder of the complex elegance of the solar system. Occurring in early January, perihelion challenges our intuitive understanding of temperature and distance, proving that the tilt of a planet’s axis is far more powerful than its orbital variance in shaping the seasons. As Earth speeds through this nearest point, racing along its elliptical track, it carries life through a predictable cycle of seasons and centuries, bound by the gravity of the Sun and governed by the immutable laws of physics.

In 2026, Earth reaches perihelion on .
For centuries, humanity believed the universe revolved around Earth in perfect circles. In the 2nd century, Claudius Ptolemy formalized this geocentric model. It wasn't until 1543 that Nicolaus Copernicus proposed the heliocentric model, placing the sun at the center.
In July, the Northern Hemisphere tilts toward the Sun. The solar rays hit us directly and intensely, driving up temperatures despite the fact that Earth is at its farthest point from the Sun. How Perihelion Influences Earth's Climate The net result: The answer is , not distance
