Light's journey
The light you see tonight set out around the year 2002. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 426 thousand years.
The Sun seen from there
From a planet around WISEPA J031325.96+780744.2, the Sun would look like a star of magnitude 4.17, in the direction where our sky has the constellation Apus. It would be visible to the naked eye.
