Light's journey
The light you see tonight set out around the year 1976. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 891 thousand years.
The Sun seen from there
From a planet around WISEPC J104245.23-384238.3, the Sun would look like a star of magnitude 5.77, in the direction where our sky has the constellation Lacerta. It would be visible to the naked eye.
