AU, or Astronomical Unit, IS a static number, despite the fact that the Earth's distance from the Sun differs during aphelion and perehelion. The AU is based on the mean Earth-Sun distance, and is exactly equal to 149,597,870.691 km.

It takes light just a little more than eight and a half minutes to travel this distance in a vacuum.
