Habitable zone

Inside the inner edge of the habitable zone: it receives 819 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 13.86. Visible from the whole Northern Hemisphere and south to latitude 57° S. North of latitude 57° N it never sets. It stands highest at midnight in August, the best time to observe it.

Light's journey

The light you see tonight set out around 318 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 42 million years.
