On July 3, 2025, Earth will arrive at aphelion, its farthest point from the Sun in its orbit. The distance between the Earth's and Sun's centers will be approximately 152,087,738 kilometers (94,502,939 miles) at this time.
Despite the increased distance, aphelion does not directly cause cooler temperatures. The tilt of Earth's axis is the primary factor influencing the seasons, determining the angle and duration of sunlight.
The Northern Hemisphere will experience summer during aphelion, while the Southern Hemisphere will be in winter. The timing of aphelion has shifted over centuries, highlighting Earth's dynamic orbital mechanics.
