Habitable zone
Inside the inner edge of the habitable zone: it receives 6.28 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 1.4° across: 2.6 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 11.44. Visible from the whole Northern Hemisphere and south to latitude 20° S. North of latitude 20° N it never sets. It stands highest at midnight in May, the best time to observe it.
Light's journey
The light you see tonight set out around the year 941. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 19 million years.
