Habitable zone
Inside the inner edge of the habitable zone: it receives 710 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 17° across: 32 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 15.36. Visible from the whole Southern Hemisphere and north to latitude 28° N. South of latitude 28° S it never sets. It stands highest at midnight in February, the best time to observe it.
Light's journey
The light you see tonight set out 4,942 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 88 million years.
