Habitable zone
Inside the inner edge of the habitable zone: it receives 819 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 14° across: 27 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 16.01. 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 June, the best time to observe it.
Light's journey
The light you see tonight set out 4,387 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 78 million years.
