This orbital path was first mathematically mapped by the 17th-century astronomer Johannes Kepler. Kepler's First Law of Planetary Motion dictates that all planets move in ellipses, with the Sun positioned at one of the focal points. Because the Sun is offset from the dead center of this oval, the Earth draws nearer to it during one half of the year and swings further away during the other.
Many people believe that the Earth is closest to the Sun during the summer months, but surprisingly, this is not the case. The Earth's orbit around the Sun is not a perfect circle, which means that the distance between the Earth and the Sun varies throughout the year. In fact, the Earth is closest to the Sun during a specific month that is often associated with cold weather.
For Earth, perihelion occurs annually in early January. During this time, the Earth is approximately 147 million kilometers (about 91.4 million miles) away from the sun. Conversely, the Earth reaches its farthest point from the sun, known as aphelion, in early July, stretching the distance to about 152 million kilometers (about 94.5 million miles). This creates a variance of roughly 5 million kilometers (3 million miles) over the course of a year. Kepler’s First Law and Elliptical Orbits

A common misconception is that the Earth's distance from the Sun dictates our seasons. If this were true, the entire planet would experience summer in January and winter in July. The Power of Axial Tilt
The Earth is closest to the Sun during the month of . This occurs around early January, when the Earth is at a point in its orbit called perihelion . At this time, the Earth is approximately 91.5 million miles (147 million kilometers) away from the Sun.
Another fascinating effect of the elliptical orbit is that Earth's orbital speed changes throughout the year. According to (also known as the Law of Equal Areas), a line connecting a planet to the Sun sweeps out equal areas in equal amounts of time. This means that when Earth is closer to the Sun, it must move faster to cover the larger arc needed to sweep out the same area. This orbital path was first mathematically mapped by
The Earth's orbit is very close to circular, with an eccentricity of about 0.017, which means the difference in distance between perihelion and aphelion is relatively small.
: Earth is closest to the Sun. It happens exclusively in early January .
This is about 5 million kilometers closer than when we are at our furthest point (Aphelion) in early July. If We’re Closer, Why Is It Cold? Many people believe that the Earth is closest
So, the Earth reaches its closest point to the Sun in , giving us a brilliant example of how intuition can be corrected by science. The planet's axial tilt, not its changing distance, is the true architect of our seasons, creating a fascinating paradox where we are closest to our star during the depths of winter. This subtle 3% difference in distance may not dictate our weather from month to month, but it adds a gentle rhythm to our seasons and plays a key role in the planet's long-term climate story.
If you are looking for the "link" between the calendar and the cosmos, remember that 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.
Because these two factors align, summers in the Southern Hemisphere can experience slightly more intense solar radiation than Northern Hemisphere summers. However, the vast oceans of the Southern Hemisphere absorb much of this excess heat, balancing out the global climate and preventing extreme temperature spikes. The Subtle Impacts of Perihelion
When Earth is at perihelion, the total sunlight hitting the planet is about 7% more intense than it is at aphelion. Globally, this provides a slight boost in solar energy, though localized weather and regional seasonal tilts largely mask its day-to-day noticeability for the average person.
