In the sky
A telescope is needed to see it: its apparent magnitude is 17.91. Visible from the whole Southern Hemisphere and north to latitude 23° N. South of latitude 23° S it never sets. It stands highest at midnight in April, the best time to observe it.

Light's journey
The light you see tonight set out around 415 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 43 million years.
The Sun seen from there
From a planet around POTS-1, the Sun would look like a star of magnitude 14.20, in the direction where our sky has the constellation Cassiopeia. It would be invisible to the naked eye.
