In the sky
A telescope is needed to see it: its apparent magnitude is 12.14. Visible from the whole Southern Hemisphere and north to latitude 35° N. South of latitude 35° 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 the year 1929. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.7 million years.
The Sun seen from there
From a planet around LHS 1815, the Sun would look like a star of magnitude 7.20, in the direction where our sky has the constellation Draco. It would be invisible to the naked eye.
