Light's journey
The light you see tonight set out around the year 1983. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 764 thousand years.
The Sun seen from there
From a planet around WISEPC J220922.10-273439.5, the Sun would look like a star of magnitude 5.43, in the direction where our sky has the constellation Leo. It would be visible to the naked eye.
