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 434 thousand years.
The Sun seen from there
From a planet around WISE J200050.19+362950.1, the Sun would look like a star of magnitude 4.21, in the direction where our sky has the constellation Puppis. It would be visible to the naked eye.
