Light's journey
The light you see tonight set out around the year 1987. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 687 thousand years.
The Sun seen from there
From a planet around GJ 414 A, the Sun would look like a star of magnitude 5.20, in the direction where our sky has the constellation Sculptor. It would be visible to the naked eye.
