Habitable zone
Inside the inner edge of the habitable zone: it receives 198 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 14.49. Visible from the whole Northern Hemisphere and south to latitude 78° S. North of latitude 78° N it never sets. It stands highest at midnight in January, the best time to observe it.
Light's journey
The light you see tonight set out around the year 582. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 26 million years.
