Light's journey
The light you see tonight set out around the year 1977. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 862 thousand years.
The Sun seen from there
From a planet around 2MASS J19010601+4718136, the Sun would look like a star of magnitude 5.70, in the direction where our sky has the constellation Puppis. It would be visible to the naked eye.
