What Is Perihelion?
Perihelion is the point in Earth's orbit when our planet comes closest to the Sun. The word comes from Greek, combining "peri," meaning near, and "helios," meaning Sun.
The Earth does not travel around the Sun in a perfect circle. Its orbit is a slight oval, or ellipse, which means there is one point each year where it is nearest the Sun and another where it is farthest away.
At perihelion, the Earth sits about 91.4 million miles from the Sun, roughly three million miles closer than at its most distant point. It happens once every year, in early January.
When Is Perihelion in 2027?
Earth reaches perihelion on Sunday, January 3, 2027. The exact date shifts by a day or two each year, usually falling in the first week of January.
This is a purely orbital event, so there is nothing to see in the sky. It is a moment marked by astronomy rather than a visible spectacle, but it reveals something surprising about how our seasons really work.
Why Is Earth Closest to the Sun in Winter?
It seems backwards that the Earth is nearest the Sun during the northern winter. If distance controlled our seasons, January should be the warmest month, not one of the coldest.
The answer is that distance is not what causes seasons. Our seasons come from the Earth's tilt, not its distance from the Sun. During northern winter, the Northern Hemisphere leans away from the Sun, so it stays cold even though the whole planet is slightly closer to the Sun at this time.
Perihelion and Aphelion
Perihelion has an exact opposite, called aphelion, the point where Earth is farthest from the Sun. Aphelion happens about six months later, in early July.
The difference between the two is small, only about three percent in distance, which is why it has little effect on our weather. Together, these two points show that the Earth's orbit is an ellipse rather than a perfect circle, a discovery that reshaped how we understand the solar system.
