In the sky
A telescope is needed to see it: its apparent magnitude is 13.84. Visible from the whole Southern Hemisphere and north to latitude 40° N. South of latitude 40° S it never sets. It stands highest at midnight in July, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 59 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 37 million years.
The Sun seen from there
From a planet around HATS-23, the Sun would look like a star of magnitude 13.86, in the direction where our sky has the constellation Lynx. It would be invisible to the naked eye.
