Light's journey
The light you see tonight set out around the year 1918. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.9 million years.
The Sun seen from there
From a planet around ULAS J025545.28+061655.8, the Sun would look like a star of magnitude 7.42, in the direction where our sky has the constellation Libra. It would be invisible to the naked eye.
