In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.26). Visible from the whole Southern Hemisphere and north to latitude 31° N. South of latitude 31° S it never sets. It stands highest at midnight in March, the best time to observe it.

Light's journey
The light you see tonight set out around the year 20. 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 53231, the Sun would look like a star of magnitude 13.77, in the direction where our sky has the constellation Cepheus. It would be invisible to the naked eye.
