In the sky
A telescope is needed to see it: its apparent magnitude is 20.50. Visible from the whole Southern Hemisphere and north to latitude 60° N. South of latitude 60° S it never sets. It stands highest at midnight in June, the best time to observe it.

Light's journey
The light you see tonight set out 10 thousand years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 181 million years.
The Sun seen from there
From a planet around KMT-2021-BLG-0119L, the Sun would look like a star of magnitude 17.31, in the direction where our sky has the constellation Auriga. It would be invisible to the naked eye.
