Habitable zone
Inside the inner edge of the habitable zone: it receives 55.6 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 13.85. Visible from the whole Northern Hemisphere and south to latitude 12° S. North of latitude 12° N it never sets.
Light's journey
The light you see tonight set out around the year 1743. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 5.0 million years.
