In the sky
A telescope is needed to see it: its apparent magnitude is 14.13. Visible from the whole Southern Hemisphere and north to latitude 50° N. South of latitude 50° S it never sets. It stands highest at midnight in November, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 1481 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 62 million years.
The Sun seen from there
From a planet around NGTS-23, the Sun would look like a star of magnitude 14.99, in the direction where our sky has the constellation Hercules. It would be invisible to the naked eye.
