What Is Aphelion?
Aphelion is the point in Earth's orbit when our planet is farthest from the Sun. The word comes from Greek, combining "apo," meaning away from, and "helios," meaning Sun.
The Earth does not orbit the Sun in a perfect circle. Its path is a slight oval, or ellipse, which means there is one point each year where it sits nearest the Sun and another where it lies farthest away.
At aphelion, the Earth is about 94.5 million miles from the Sun, roughly three million miles farther than at its closest point. It happens once every year, in early July.
When Is Aphelion in 2027?
Earth reaches aphelion on Sunday, July 4, 2027. The exact date shifts by a day or two each year, usually falling in the first week of July.
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 points to a surprising truth about our seasons.
Why Is Earth Farthest From the Sun in Summer?
It seems strange that the Earth is farthest from the Sun during the northern summer. If distance controlled our seasons, July should be one of the coldest months, not one of the warmest.
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 summer, the Northern Hemisphere leans toward the Sun, so it stays warm even though the whole planet is slightly farther from the Sun at this time.
Aphelion and Perihelion
Aphelion has an exact opposite, called perihelion, the point where Earth is closest to the Sun. Perihelion happens about six months earlier, in early January.
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 prove that the Earth's orbit is an ellipse rather than a perfect circle, a fact that reshaped our understanding of the solar system.
