Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1316. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 13 million years.
The Sun seen from there
From a planet around HIP 47168, the Sun would look like a star of magnitude 11.52, in the direction where our sky has the constellation Piscis Austrinus. It would be invisible to the naked eye.
