Earth Reaches 94.4 Million Miles From the Sun on July 6 as Northern Summer Peaks

Q: Why does our summer become the year's longest season when Earth is farthest from the Sun?

Summer is the longest season in the Northern Hemisphere because Earth moves slowest in its orbit when it is farthest from the Sun, near aphelion. The key point is that distance from the Sun does not create the seasons. Summer happens because Earth’s axis is tilted about 23.5 degrees, so the Northern Hemisphere is angled toward the Sun in June and July, receiving more direct sunlight and longer daylight hours. That tilt matters far more than the roughly 3% change in Earth-Sun distance between perihelion and aphelion. What aphelion changes is not the existence of summer, but its length. Earth’s orbit is slightly elliptical, and under Kepler’s Second Law, a planet travels faster when it is closer to the Sun and slower when it is farther away. Around early July, when Earth reaches aphelion at about 152.1 million kilometers from the Sun, it is moving at its slowest annual orbital speed. Because the Northern Hemisphere’s summer overlaps with this slower part of Earth’s orbit, the planet takes longer to move from one seasonal marker to the next. That is why northern summer lasts longer than northern winter, which occurs near perihelion in early January, when Earth is moving faster. In practical terms, the March-to-September half of the year lasts about 186 days, compared with about 179 days from September to March. That orbital timing makes northern summer the longest season of the year, by nearly five days.

July 6 at about 17:30 UTC marks Earth’s 2026 aphelion, when the planet will sit roughly 94.4 million miles, or 152.1 million km, from the Sun.
NASA says the event reflects Earth’s elliptical orbit, with aphelion only about 3 million miles farther than perihelion—roughly a 3% gap from the average Earth-Sun distance.
A 23.5-degree Axial tilt, not that extra distance, drives Northern Hemisphere summer by aiming more direct sunlight northward even as Earth is farthest from the Sun.
That same orbital geometry also slows Earth slightly near aphelion, helping make Northern Hemisphere summer the longest season; perihelion returns in early January at about 147 million km.
