Habitable zone

Inside the inner edge of the habitable zone: it receives 2.09 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 10.83. Visible from the whole Southern Hemisphere and north to latitude 43° N. South of latitude 43° S it never sets. It stands highest at midnight in July, the best time to observe it.

Light's journey

The light you see tonight set out around the year 915. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 20 million years.
