While completing their orbit they come closer to its focus (The Sun) and are sometimes at the farthest location. The Earth in a similar fashion revolves around the Sun and comes closer to the Sun, the closest point to the Sun is known as perihelion. It generally occurs on January 3 every year. When the Earth is at the farthest location from the Sun it is known as Aphelion which generally falls on July 04.
