Light's journey
The light you see tonight set out around the year 724. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 23 million years.
The Sun seen from there
From a planet around TIC 87422071, the Sun would look like a star of magnitude 12.84, in the direction where our sky has the constellation Auriga. It would be invisible to the naked eye.
