What is the distance from the earth to the sun?

The average distance from the Earth to the Sun is about 149.6 million kilometres (149,597,870 km). This distance is known as 1 Astronomical Unit (AU).

Because Earth's orbit is slightly elliptical, the actual distance varies throughout the year. The Earth is closest to the Sun (perihelion) in early January and farthest from the Sun (aphelion) in early July.

This average distance is used as a standard unit for measuring distances within the Solar System.
