In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.13). Visible from the whole Northern Hemisphere and south to latitude 25° S. North of latitude 25° N it never sets. It stands highest at midnight in November, the best time to observe it.

Light's journey
The light you see tonight set out around the year 35. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 35 million years.
The Sun seen from there
From a planet around HIP 15890, the Sun would look like a star of magnitude 13.76, in the direction where our sky has the constellation Triangulum Australe. It would be invisible to the naked eye.
