In the sky
A telescope is needed to see it: its apparent magnitude is 9.16. Visible from the whole Southern Hemisphere and north to latitude 78° N. South of latitude 78° S it never sets. It stands highest at midnight in February, the best time to observe it.

Light's journey
The light you see tonight set out around the year 28. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 35 million years.
The Sun seen from there
From a planet around Gl 369, the Sun would look like a star of magnitude 13.77, in the direction where our sky has the constellation Pegasus. It would be invisible to the naked eye.
