Habitable zone

Inside the inner edge of the habitable zone: it receives 75 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 14.13. Visible from the whole Southern Hemisphere and north to latitude 42° N. South of latitude 42° S it never sets. It stands highest at midnight in November, the best time to observe it.

Light's journey

The light you see tonight set out around the year 1214. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 14 million years.
