The period when the earth is furthest from the sun is

The period when the Earth is furthest from the sun is called "Aphelion." The Earth orbits the sun in an elliptical (oval-shaped) path, which means that its distance from the sun changes over the course of a year. At one point, it is closest to the sun and at another, it is furthest away. The point when the Earth is furthest from the sun is called Aphelion and it usually occurs around July 4th. This is because the Earth's orbit is tilted relative to its rotational axis, which causes the Earth to be closest to the sun during the Northern Hemisphere's winter and furthest from the sun during the Northern Hemisphere's summer.
