In the sky
A telescope is needed to see it: its apparent magnitude is 13.33. Visible from the whole Southern Hemisphere and north to latitude 68° N. South of latitude 68° S it never sets. It stands highest at midnight in December, the best time to observe it.

Light's journey
The light you see tonight set out around 493 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 45 million years.
The Sun seen from there
From a planet around HATS-45, the Sun would look like a star of magnitude 14.27, in the direction where our sky has the constellation Hercules. It would be invisible to the naked eye.
