how far is the earth from the sun

The Earth is on average about 149.6 million kilometers (approximately 93 million miles) away from the Sun. This distance is also defined as 1 astronomical unit (AU), a standard measure used in astronomy to describe distances within the solar system. The Earth's orbit is slightly elliptical, so this distance varies slightly throughout the year, ranging from about 147.1 million km at its closest (perihelion) to about 152.1 million km at its farthest (aphelion).
