In the sky
A telescope is needed to see it: its apparent magnitude is 31.11. Visible from the whole Southern Hemisphere and north to latitude 56° N. South of latitude 56° S it never sets. It stands highest at midnight in June, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out 19 thousand years ago. At that time Homo sapiens was spreading out of Africa; there was no farming yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 329 million years.
The Sun seen from there
From a planet around MOA-2009-BLG-387L, the Sun would look like a star of magnitude 18.61, in the direction where our sky has the constellation Auriga. It would be invisible to the naked eye.
