The Earth is on average about 149.6 million kilometers (approximately 93 million miles) away from the Sun. This distance is commonly referred to as one astronomical unit (AU), which is a standard unit used to measure distances in the solar system. Earth's orbit around the Sun is slightly elliptical, so this distance varies slightly throughout the year, ranging from about 147.1 million km (91.4 million miles) at its closest (perihelion) to about 152.1 million km (94.5 million miles) at its farthest (aphelion).
This distance means that sunlight takes about 8 minutes and 20 seconds to travel from the Sun to Earth.
