how far is sun from earth

The average distance from the Sun to the Earth is about 93 million miles, or approximately 150 million kilometers. This distance is also known as one astronomical unit (AU). Due to Earth's elliptical orbit, this distance varies slightly throughout the year, ranging from about 91 million miles (147 million km) at its closest (perihelion) to about 94.5 million miles (152 million km) at its farthest (aphelion). On average, light from the Sun takes about 8 minutes to reach Earth.
