In the sky
A telescope is needed to see it: its apparent magnitude is 13.35. Visible from the whole Southern Hemisphere and north to latitude 65° N. South of latitude 65° S 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 192 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 39 million years.
The Sun seen from there
From a planet around HATS-61, the Sun would look like a star of magnitude 13.99, in the direction where our sky has the constellation Serpens. It would be invisible to the naked eye.
