In the sky
A telescope is needed to see it: its apparent magnitude is 10.50. Visible from the whole Southern Hemisphere and north to latitude 89° N. It stands highest at midnight in August, the best time to observe it.

Light's journey
The light you see tonight set out around the year 887. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 20 million years.
The Sun seen from there
From a planet around GJ 4286, the Sun would look like a star of magnitude 12.55, in the direction where our sky has the constellation Sextans. It would be invisible to the naked eye.
