Light's journey
The light you see tonight set out around the year 1975. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 903 thousand years.
The Sun seen from there
From a planet around SDSS J151603.03+025928.9, the Sun would look like a star of magnitude 5.80, in the direction where our sky has the constellation Eridanus. It would be visible to the naked eye.
