Light's journey
The light you see tonight set out around the year 1973. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 947 thousand years.
The Sun seen from there
From a planet around 2MASS J21265916+7617440, the Sun would look like a star of magnitude 5.90, in the direction where our sky has the constellation Chamaeleon. It would be visible to the naked eye.
