In the sky
A telescope is needed to see it: its apparent magnitude is 12.24. Visible from the whole Northern Hemisphere and south to latitude 17° S. North of latitude 17° N it never sets. It stands highest at midnight in July, the best time to observe it.
Light's journey
The light you see tonight set out around the year 700. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 24 million years.
