In the sky
A telescope is needed to see it: its apparent magnitude is 28.25. Visible from the whole Southern Hemisphere and north to latitude 59° N. South of latitude 59° S 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 around 617 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 47 million years.
