Habitable zone
Inside the inner edge of the habitable zone: it receives 2,890 times the light the Earth does, too hot to keep liquid water on its surface.
In the sky
A telescope is needed to see it: its apparent magnitude is 12.66. Visible from the whole Southern Hemisphere and north to latitude 58° N. South of latitude 58° 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 79 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 37 million years.
