In the sky
A telescope is needed to see it: its apparent magnitude is 13.69. Visible from the whole Southern Hemisphere and north to latitude 28° N. South of latitude 28° S it never sets. It stands highest at midnight in November, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1092. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 17 million years.
