SPACEWEATHER: Earth Reaches Aphelion, Arriving Sunspot 4482, Nature’s Fireworks

Earth’s Farthest Distance from the Sun

Earth reached Aphelion today, July 6, 2026, at 17:30 UTC (12:30 PM CDT). The Days of Earth’s Perihelion and Aphelion positions are significant astronomical measures, though they are rarely acknowledged in the news.

  • Aphelion is the point of the Earth’s orbit that is farthest away from the Sun. It always happens in early July, about 2 weeks after the June solstice,
  • Perihelion is the point of the Earth’s orbit that is nearest to the Sun. This always happens in early January, about 2 weeks after the December Solstice.

The words come from ancient Greek, in which helios means “Sun,” apo means “far,” and peri means “close.”

At Aphelion, Earth was roughly 94.5 million miles (152.1 million kilometers) away from the Sun, about 3.1 million miles farther than at its closest point (perihelion). Despite being at its farthest point from the Sun, the entire planet actually receives about 7% less intense sunlight, though the distance does not dictate the seasons. Summer in the Northern Hemisphere is caused by the planet’s 23.5-degree axial tilt, which points the northern half of the globe towards the Sun for longer, warmer days.  (Old Farmer’s Almanac)

SPACEWEATHER: Earth-facing Sunspot AR3712 increased 10-fold in the past 48 hours

SPACEWEATHER.COM NEWS: JUNE 15, 2024

A POTENTIALLY DANGEROUS SUNSPOT: New sunspot AR3712 has increased in size 10-fold in the past 48 hours: movie. The fast-growing active region has a mixed-polarity magnetic field that harbors energy for X-class solar flares. Any such eruptions this weekend will be geoeffective as the sunspot is turning to directly face Earth.
