Habitable zone
Inside the inner edge of the habitable zone: it receives 58.7 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 8.4° across: 16 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 17.91. Visible from the whole Southern Hemisphere and north to latitude 23° N. South of latitude 23° S it never sets. It stands highest at midnight in April, the best time to observe it.
Light's journey
The light you see tonight set out around 415 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 43 million years.
