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.

This morning at perihelion both hemispheres were 147.5 million km from the Sun. That barely differs from the greatest distance, 152.6 million km in July, which astronomers call aphelion. Perihelion always occurs near January 4th, while aphelion lands near the 4th of July.

aphelion and perihelion differ from the mean Sun-Earth distance by less than 2%. In fact, if you drew Earth's orbit on a sheet of paper it would be difficult to distinguish from a perfect circle.
