The point on Earth closest to the Sun varies throughout the year due to the Earth's elliptical orbit around the Sun. This point is called the perihelion. The Earth's orbit is not a perfect circle, but rather an ellipse with the Sun located at one of its foci.

The Earth reaches perihelion around early January each year. The specific location on Earth closest to the Sun at that time depends on various factors such as the tilt of the Earth's axis and its position within its annual orbit.

While the distance to the Sun varies slightly during the year, it doesn't have a significant impact on the climate or daily life at specific locations on Earth. The tilt of the Earth's axis and its rotation play more significant roles in determining seasons and climate patterns.

It's worth noting that the difference in distance to the Sun between perihelion and aphelion (the point farthest from the Sun) is relatively small—about 3.1 million miles or 5 million kilometers.
