Light's journey
The light you see tonight set out around the year 427. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 28 million years.
The Sun seen from there
From a planet around HIP 23680, the Sun would look like a star of magnitude 13.28, in the direction where our sky has the constellation Ophiuchus. It would be invisible to the naked eye.
