Light's journey
The light you see tonight set out around the year 1993. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 578 thousand years.
The Sun seen from there
From a planet around HD 260655, the Sun would look like a star of magnitude 4.83, in the direction where our sky has the constellation Sagittarius. It would be visible to the naked eye.
