Light's journey
The light you see tonight set out around the year 1406. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 11 million years.
The Sun seen from there
From a planet around Cha 130540-773958, the Sun would look like a star of magnitude 11.22, in the direction where our sky has the constellation Cassiopeia. It would be invisible to the naked eye.
