Light's journey
The light you see tonight set out around the year 1990. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 636 thousand years.
The Sun seen from there
From a planet around CWISE J172617.09-484424.9, the Sun would look like a star of magnitude 5.04, in the direction where our sky has the constellation Auriga. It would be visible to the naked eye.
