Habitable zone

Inside the inner edge of the habitable zone: it receives 3.9 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 13.59. 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 January, the best time to observe it.

Light's journey

The light you see tonight set out around the year 1728. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 5.3 million years.
