Light's journey
The light you see tonight set out around the year 1985. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 728 thousand years.
The Sun seen from there
From a planet around HD 69830, the Sun would look like a star of magnitude 5.33, in the direction where our sky has the constellation Delphinus. It would be visible to the naked eye.
