Why Earth Is Farthest from the Sun in July — Yet Summer Is at Its Peak

On July 6, 2026, at 17:30 UTC, or about 1:30 p.m. EDT, Earth reaches aphelion—its farthest point from the Sun for the year. The U.S. Naval Observatory lists Earth’s 2026 aphelion at exactly that date and time.

That may sound surprising at first. After all, July is hot across much of North America. So how can Earth be farthest from the Sun during the same time many of us are sweating through long summer afternoons?

The answer is one of the most important lessons in basic astronomy: our seasons are caused by the tilt of Earth’s axis, not by how close we are to the Sun.

Earth does not orbit the Sun in a perfect circle. Its path is slightly oval-shaped, which means there is one point each year when Earth is closest to the Sun, called perihelion, and one point when it is farthest away, called aphelion. In 2026, aphelion falls on July 6. At that moment, Earth will be about 1.0166 astronomical units from the Sun.

But that distance change is small compared with the overall scale of Earth’s orbit. It is not enough to drive the seasons.

Instead, summer and winter happen because Earth is tilted on its axis. As Earth travels around the Sun, different parts of the planet receive more direct sunlight at different times of year. When the Northern Hemisphere is tilted toward the Sun, sunlight hits it more directly and days are longer. That gives us summer. When the Northern Hemisphere tilts away, sunlight is less direct and days are shorter, bringing winter. NASA explains that Earth’s tilted axis is the reason we have seasons.

So even though Earth is farthest from the Sun in early July, the Northern Hemisphere is still tilted toward the Sun. That tilt gives us longer days, stronger sunlight, and warmer weather.

Aphelion is a great reminder that space does not always work the way it feels from the ground. The Sun may seem especially intense in July, but on July 6, we are actually as far from it as we will be all year.

Sometimes, the best astronomy facts are the ones that make us pause and look twice.
