Question

How many light years away is the sun from earth?

Answer 1

`1.58xx10^-5` light years

Explanation:

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!`
