In the sky
A telescope is needed to see it: its apparent magnitude is 14.98. Visible from the whole Northern Hemisphere and south to latitude 46° S. North of latitude 46° N it never sets. It stands highest at midnight in June, the best time to observe it.
Light's journey
The light you see tonight set out 4,185 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 74 million years.
