The Surprising Truth: When is Earth Closest to the Sun? If you live in the Northern Hemisphere, you might assume that Earth is closest to the sun during the sweltering heat of July. It seems logical—the closer you are to a fire, the warmer you feel. However, celestial mechanics are often counterintuitive.
This is the point where Earth is farthest from the sun, roughly 152 million kilometres (94.5 million miles) away. This occurs in early July . Why Isn't It Hotter in January?

It is a common misconception that the Earth's distance from the Sun causes the seasons. If that were true, the entire planet would experience summer at the same time. month when earth is closest to the sun
The month when the Earth is closest to the Sun is .
The ~3% difference in distance has only a small effect on global average temperatures (slightly milder winters in the north, slightly milder summers in the south), but it is by the tilt's effect on sunlight angle and day length.
Derived from the Greek words peri (near) and helios (sun), this occurs when Earth is roughly 147 million kilometres (91.4 million miles) from the sun. This typically happens between January 2nd and January 5th . The Surprising Truth: When is Earth Closest to the Sun
Because Earth moves faster at perihelion, winter in the Northern Hemisphere is about five days shorter than summer.
The sun appears about 3% larger in the sky, and the sunlight reaching Earth is approximately 7% more intense than at its farthest point.
The month when the Earth is closest to the sun is . This orbital point is known as perihelion . However, celestial mechanics are often counterintuitive
Sunlight is roughly 7% more intense at perihelion than at aphelion, though the tilt of the Earth and the distribution of landmasses (which heat up faster than oceans) usually mask this effect. The Big Picture
While the change in distance doesn't cause the seasons, it does have subtle effects:
