In the sky
A telescope is needed to see it: its apparent magnitude is 12.20. Visible from the whole Southern Hemisphere and north to latitude 77° N. South of latitude 77° S it never sets. It stands highest at midnight in January, the best time to observe it.

Light's journey
The light you see tonight set out around 3 BC. 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 WASP-169, the Sun would look like a star of magnitude 13.80, in the direction where our sky has the constellation Delphinus. It would be invisible to the naked eye.
