Earth reaches perihelion in early January each year, and passes through its aphelion point near the start of July. At perihelion, our planet is about 147 million km (91 million miles) from the Sun; it moves outward to around 152 million km (95 million miles) from the Sun at aphelion.

At perihelion Earth is approximately 91.4 million miles from the sun, whereas at aphelion—the farthest point in Earth's orbit—Earth is 94.5 million miles from the sun. In 2010 Earth's reaches aphelion on July 6. It might seem strange that Earth is closest to the sun during winter and farthest away in summer,

July 3, 2001 On the 4th of July Earth will be at its greatest distance from the Sun this year. But don't expect any sudden relief from the heat, say scientists. Northern summer will continue unabated --perhaps even worse than usual-- despite our arrival at a distant part of Earth's orbit called "aphelion."

An overview of the earth's orbit around the sun, including the times when it is closest to the sun and farthest from the sun, known as perihelion and aphelion, respectively. ... The earth's orbit around the sun is not a circle. The earth's orbit around the sun is slightly elliptical. Therefore, the distance between the...
