This means the distance between the Earth and the sun varies throughout the year. When the Earth is closest to the sun, it is in what is called perihelion. When it is farthest from the sun, it is in aphelion. Earth's orbit takes about 365.25 days to complete, which is why we have a leap year every four years. The study of the Earth's orbit is essential for understanding climate and weather patterns, as well as for space exploration.
