In the sky
A telescope is needed to see it: its apparent magnitude is 10.90. Visible from the whole Northern Hemisphere and south to latitude 88° S. It stands highest at midnight in June, the best time to observe it.

Light's journey
The light you see tonight set out around the year 716. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 23 million years.
The Sun seen from there
From a planet around GJ 4006, the Sun would look like a star of magnitude 12.85, in the direction where our sky has the constellation Orion. It would be invisible to the naked eye.
