Habitable zone
Inside the inner edge of the habitable zone: it receives 6,230 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 31° across: 57 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 10.94. Visible from the whole Southern Hemisphere and north to latitude 60° N. South of latitude 60° S it never sets. It stands highest at midnight in October, the best time to observe it.
Light's journey
The light you see tonight set out around the year 608. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 25 million years.
