Earth got farther from the sun yesterday (July 3) than at any other point during the year. The moment of greatest separation between the Sun and the Earth, known as aphelion, was at 4:11 p.m. EDT (2011 GMT) today, when Earth and the sun were 94,505,901 miles (152,092,505 kilometers) apart.

On average, Earth lies 92,955,807 miles (149,597,870 km) from its star, a distance that has been designated 1 astronomical unit (AU). But the actual separation between the duo varies a bit over time, because Earth’s orbital path is not perfectly circular.
