In the sky
A telescope is needed to see it: its apparent magnitude is 17.59. Visible from the whole Southern Hemisphere and north to latitude 12° N. South of latitude 12° S it never sets.
Light's journey
The light you see tonight set out around the year 1405. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 11 million years.
