In the sky

A telescope is needed to see it: its apparent magnitude is 14.32. Visible from the whole Northern Hemisphere and south to latitude 51° S. North of latitude 51° 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 1940 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 70 million years.
