Point Sun Date __top__ | Earth Closest
The date when Earth is closest to the Sun is called . This occurs every year in early January , typically on January 3rd or 4th .
Interestingly, because Earth is closer to the Sun during perihelion, it moves slightly faster in its elliptical orbit (thanks to Kepler’s laws of planetary motion). This means Northern Hemisphere winters are a few days shorter and milder than Southern Hemisphere winters — a small but measurable effect. | Event | Date (approx.) | 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 | Fun Fact Despite being closer to the Sun in January, Earth receives about 6–7% more solar radiation at perihelion than at aphelion. Yet, the Southern Hemisphere’s oceans and land distribution absorb and release heat differently, which helps moderate the climate. earth closest point sun date
So the next time you’re bundling up in January, remember: our planet is actually making its annual close pass by the Sun — a cosmic reminder that distance isn’t everything. The date when Earth is closest to the Sun is called
At that moment, Earth is approximately from the Sun — about 1.6 million miles (2.6 million km) closer than at its farthest point, or aphelion , which occurs in early July. Why Does Perihelion Happen in Winter? The seasons are not caused by our distance from the Sun, but by Earth’s axial tilt (about 23.5 degrees). In January, the Northern Hemisphere is tilted away from the Sun, receiving less direct sunlight and shorter days — hence, winter. Meanwhile, the Southern Hemisphere is tilted toward the Sun, enjoying summer. This means Northern Hemisphere winters are a few
Here’s a well-prepared explanation: While you might expect the closest approach to happen during a sweltering summer, Earth actually reaches its nearest point to the Sun in the dead of winter for the Northern Hemisphere. This date, known as perihelion , usually falls on January 3rd or 4th .
