Habitable zone
Inside the inner edge of the habitable zone: it receives 130 times the light the Earth does, too hot to keep liquid water on its surface.
Its star in the sky
In the planet's sky its star is a disc 12° across: 23 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 16.68. Visible from the whole Southern Hemisphere and north to latitude 58° N. South of latitude 58° 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 768. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 22 million years.
