The exact distance between Earth and the Sun varies with its position in its orbit, which is elliptical. The average distance (the mean distance) between the Earth and the Sun is about 150 million kilometers (93 million miles).
The average distance from the Earth to the Sun is also called 1 astronomical unit (or AU). This is established as 149,597,870.7 kilometers (92,955,887.6 miles).
Aphelion (when the Earth is the farthest from the Sun) occurs around the first week of July. The distance is about 152 million km (94.4 million miles).
Perihelion (when the Earth is closest to the Sun) occurs in the first week of January. The distance is about 147 million km (91.3 million miles).

The average distance between the sun and the earth is 149 million kilometers (93 million miles).

Because of earth's elliptical orbit around the sun, the distance changes over the course of a year (one complete orbit of the sun):

We are closest at perihelion, during winter in the Northern Hemisphere (around January 3rd) at the minimum distance of 147 million km (91 million miles).

We are farthest away at aphelion, during summer in the Northern Hemisphere (around July 4th) at the maximum distance of 152 million km (94.5 million miles).

Light from the sun takes roughly 8 minutes to reach the earth traveling, of course, at the speed of light. Therefore you can say the sun is 8 light minutes away from the earth, just as you can say a star is light years away.
