Light's journey
The light you see tonight set out around the year 1971. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 972 thousand years.
The Sun seen from there
From a planet around WISE J112438.12-042149.7, the Sun would look like a star of magnitude 5.96, in the direction where our sky has the constellation Pisces. It would be visible to the naked eye.
