Light's journey
The light you see tonight set out around the year 17. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 36 million years.
The Sun seen from there
From a planet around HIP 105334, the Sun would look like a star of magnitude 13.78, in the direction where our sky has the constellation Ursa Major. It would be invisible to the naked eye.
