Earth will be at aphelion, its furthest orbital distance from the Sun, around midnight on 3 July. It will then be 152,095,745 km from the Sun, compared with its minimum distance from the Sun (perihelion) of 147,103, 622 km in January.

Since the eccentricity of our planet’s orbit is very small and the orbit is nearly circular, aphelion and perihelion differ from the mean Sun-Earth distance by less than 2%. If you drew Earth’s orbit on a sheet of paper it would be difficult to distinguish from a perfect circle.
Since Earth is at its furthest from the Sun, average global sunlight arriving in July is about 7% less intense than it is in January. However, the average temperature of Earth at aphelion is about 2.3C higher than it is at perihelion - Earth is actually warmer when it is further from the Sun.

This is because our planet has more land in the northern hemisphere and more water in the south. During July – in the northern summer - the mainly continental northern half of our planet is tilted toward the Sun, and the land masses heat up more easily than the oceans.
