The approximate distance of the Earth from the sun is about 93 million miles, or 150 million kilometers. This distance is also referred to as one astronomical unit (AU), a standard measurement used in astronomy to express distances within our solar system. The Earth orbits the sun in an elliptical path, causing slight variations in distance throughout the year, but the average remains close to this figure. This distance is critical for maintaining the planet's climate and supporting life. Understanding this relationship between the Earth and the sun is fundamental to the study of astronomy and planetary science.
