The astronomical unit (AU) is based on the long-term average distance between the Sun and Earth. It is approximately 150 million kilometres.
It is defined as 149,597,871.5 km.
This is the distance at which a small object on a perfectly circular orbit would have an orbital period equal to the average year of Earth.
In December, we are usually a bit closer to the Sun than in July. On January 2, in the early evening, we will be at our closest to the Sun (on this year's orbit) at 147,096,448 km. This point is called perihelion (from Greek words meaning close to the Sun)
On July 4 (early morning) we'll be at aphelion (furthest point) at 152,104,136 km.
These numbers are centre to centre.
If you are on Earth's surface directly underneath the Sun and consider the distance to the surface of the Sun closest to you, then the total distance could be a little less.
Sunlight takes 499 seconds to reach us (on average -- meaning at 1 AU).

Approximately 93 million miles. Or 1 A.U. Astronomical Unit.
It also takes 8 minutes for light to get to the earth from the sun.

the right distance between Earth and the sunlight varies with its place in its orbit, that's elliptical. the straightforward distance (the recommend distance) between the Earth and the sunlight is approximately a hundred and fifty million kilometers (ninety 3 million miles).
