Habitable zone
Inside the inner edge of the habitable zone: it receives 116 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
Too faint for the naked eye (magnitude 8.15); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 46° S. North of latitude 46° N it never sets. It stands highest at midnight in March, the best time to observe it.
Light's journey
The light you see tonight set out around 182 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 39 million years.
