#1.58xx10^-5# light years


The distance between the Sun and Earth has a medium value of 1 AU which is 149597871 km. If we divide this by the light velocity (299792458 m/s) we will obtain:

#(149597871xx10^3)/299792458=499# seconds=8 minutes and 19 seconds!

So the Sun is 8 light-minutes from the Earth.

Light-years is a unsuitable measure to use in the solar system.

The Sun-Earth distance is:

#499/(365.25*24*3600)=1.58xx10^-5 light years!#
