In the sky
A telescope is needed to see it: its apparent magnitude is 15.25. Visible from the whole Southern Hemisphere and north to latitude 66° N. South of latitude 66° S it never sets. It stands highest at midnight in February, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1896. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.3 million years.
