Habitable zone
Inside the inner edge of the habitable zone: it receives 1,430 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 12.38. Visible from the whole Southern Hemisphere and north to latitude 23° N. South of latitude 23° S it never sets. It stands highest at midnight in December, the best time to observe it.
Light's journey
The light you see tonight set out around 546 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 46 million years.
